Deu 13:1 If there should arise in the midst of you a prophet or a 
	  dreamer of dreams, and he gives you a sign or a wonder- 
	  "If" could as well be translated "when". Paul seems to allude here: 
	  "Of your own selves shall men arise, speaking perverse things" (Acts 
	  20:30). Jeremiah feared God had deceived him (Jer. 20:7)- showing 
	  he knew such a thing was possible. Dt. 13:1-3 warns Israel not to believe 
	  prophets whose prophecies came true although they taught false doctrines, 
	  because they may have been raised up to test their obedience. God deceived 
	  Israel by telling them about the peace which would come on Jerusalem in 
	  the future Kingdom; they didn't consider the other prophecies which 
	  were given at the same time concerning their imminent judgment, and 
	  therefore they thought that God was pleased with them and was about to 
	  establish the Messianic Kingdom; when actually the very opposite was about 
	  to happen (Jer. 4:10). This is why the Bible is confusing to those who 
	  aren’t humble to God’s word. 
	  
	  Deu 13:2 and the sign or the wonder comes to pass of which he spoke to you 
	  saying, Let us go after other gods (which you have not previously known) 
	  and let us serve them- 
	  The idea is that 'if the miracle appears to happen'. But that is not 
	  stated- the argument assumes, for a moment, that the alleged miracle 
	  actually happened. The idea is that the false prophet would do fake 
	  miracles in order to back up his appeal to serve other gods. Yahweh often 
	  makes the point that the signs and wonders He did for His people were far 
	  greater than anything ever seen upon earth. Likewise, the sheer magnitude 
	  of the Lord's miracles of themselves showed that all belief in demons as 
	  sources of power was utterly inappropriate. But the New Testament record 
	  assumes, for a moment, that demons had some power. Even though in reality 
	  they have no existence. And so here, for a moment, for the sake of 
	  argument, it is assumed that the alleged wonders were genuine and not 
	  fake.
We observe in this passage how empirical evidence isn't necessarily the 
	  basis for faith. Even if it apparently exists in the form of fulfilled 
	  prophecy, so it apparently can for others who teach falsely.
	  The classic Biblical explanation 
	  of faith is in Hebrews 11:1-3: “Now faith is assurance of things 
	  hoped for, the evidence about invisible things… By faith we understand 
	  that the ages have been framed by the word of God, so that what is seen 
	  has not been made out of things which appear”. Putting meaning into words, 
	  this at first blush is circular reasoning. Faith is the evidence. But on 
	  what evidence are we to believe? Faith is the evidence. The Hebrew writer 
	  was no simplistic fool. He [or she] was surely aware that this is 
	  apparently circular reasoning. Faith is the evidence. So, faith is not 
	  evidence-based. You believe on the basis of faith. The same kind of 
	  apparently circular reasoning is found often in the Bible. Once you are on 
	  the look out for it. Take 1 Jn. 5:13: “These things have I written unto 
	  you that believe on the name of the Son of God; that you may… believe on 
	  the name of the Son of God”. 
	  Deu 13:3 you must not listen to the words of that prophet or to that 
	  dreamer of dreams, for Yahweh your God proves you-
	  The reasoning here is helpful with respect to the claims made by some 
	  to perform supernatural feats. Even if it seems they might have done so, 
	  that isn’t a good enough reason to believe them; our loyalty to the one 
	  true God must not be swayed by apparently impressive deeds or predictions 
	  by those who don’t believe in Him. 
To know whether you 
	  love Yahweh your God with all your heart and with all your soul-
	  Yahweh was to be loved with all the heart, soul and mind (Dt. 6:5). 
	  This is understood by Joshua as meaning that those who loved Yahweh would 
	  not "mix with" and intermarry with the nations and accept their gods 
	  (Josh. 23:11,12,16). "Love" for God was not therefore a feeling; Joshua 
	  said that they must "take good heed therefore to yourselves, that you love 
	  Yahweh" (Josh. 23:11). This is the love of conscious direction of the 
	  mind, the love which is a choice rather than an emotion.    
Time and again, Moses speaks of the state of their heart. He warns them against allowing a bad state of heart to develop, he speaks often of how apostasy starts in the heart. Moses makes a total of 49 references to the heart / mind of Israel in Deuteronomy, compared to only 13 in the whole of Exodus, Leviticus and Numbers. This indicates the paramount importance which our Lord attaches to the state of our mind. This was perhaps his greatest wish as He faced death; that we should develop a spiritual mind and thereby manifest the Father and come to salvation. Moses likewise saw the state of our mind as the key to spiritual success. But do we share this perspective? Do we guard our minds against the media and influence of a mind-corrupting world? It's been observed that the phrase "The God of [somebody]", or similar, occurs 614 times in the Old Testament, of which 306 are in Deuteronomy. Our very personal relationship with God was therefore something else which Moses came to grasp in his spiritual maturity. Statistical analysis of the word "love" in the Pentateuch likewise reveals that "love" was a great theme of Moses at the end of his life (Moses uses it 16 times in Deuteronomy, and only four times in Exodus, Leviticus and Numbers).
	  Deu 13:4 You must walk after Yahweh your God and fear Him and keep His 
	  commandments and obey His voice- 
	  
	  
And you must serve Him and cleave to Him-
	  
	  The idea of 'cleaving' to God is a big theme of Moses in Deuteronomy 
	  (Dt. 4:4; 10:20; 11:22; 13:4,17; 28:21,60; 30:20); the only other time 
	  Moses uses the word in his writings is in Gen. 2:24, concerning a man 
	  cleaving to his wife. Moses seems to have been suggesting to Israel that 
	  their covenant relationship with God meant they were 
	  marrying God. This was a real 
	  paradigm breaker. We may be used to such things. But against the 
	  theological background of the time, not to say the generally low level of 
	  spirituality among Israel, this was a shocking idea. It reflected the 
	  heights to which Moses had risen.  
	  
“If you love me you will 
	  keep my commandments” (Jn. 14:15,21,23; 15:10) reflects a major identical 
	  theme in Dt. 5:10; 7:9; 11:1,22; 13:3,4; 19:9; 30:16. 
	  Moses at the end of his life, when he spoke Deuteronomy, was very much the 
	  image of the future Lord Jesus. 
	  Deu 13:5 That prophet or that dreamer of dreams must be put to death, 
	  because he has spoken rebellion against Yahweh your God, Who brought you 
	  out of the land of Egypt and redeemed you out of the house of bondage, to 
	  draw you aside out of the way which Yahweh your God commanded you to walk 
	  in. So you must put away the evil from the midst of you- 
	  Moses' frequent references to the way in which the Exodus had 
	  separated Israel from Egypt show the colossal difference there is between 
	  us and this world as a result of our Red Sea baptism into Christ (13:5; 
	  15:15; 16:12; 1 Cor. 10:1,2); as our Lord in His time of dying was so 
	  strongly aware of the way in which He was redeeming us from this present 
	  evil world (Gal. 1:4). 
	  Deu 13:6 If your brother, the son of your mother, or your son or your 
	  daughter, or the wife of your bosom or your friend, who is as your own 
	  soul, entices you secretly, saying, Let us go and serve other gods, which 
	  you have not known, you nor your fathers-
	  Moses  speaks as if he assumed that surely Israel would love 
	  their neighbour as themselves: "Thy brother...or thy friend, which is as 
	  thine own soul" almost unconsciously reveals the depth of Moses' positive 
	  faith in their obedience, even though on the other hand he clearly 
	  understood their future apostacy. So often family loyalties deflect a 
	  person from their loyalty to the one true God. The same has always been 
	  the case. Our spiritual family should ultimately be more meaningful to us 
	  than our natural family; that at least is the ideal, although all families 
	  have their dysfunctions, including our spiritual family.
	  Despite omitting some of the Law's commands in his speech, there are other  commands which Moses really 
	  emphasizes and repeats within his speech; e.g. the  need to destroy idols and false teachers, and to provide cities of refuge to  cater for the sins they would commit without intending to (Dt. 7:5; 12:3,  23-25; 13:6-14 = 17:2-7). This surely reflects our Lord's attitude to us; it is  his desire that we 
	  recognize our sinfulness, our likelihood of failure, our  need to separate from things which will lead us away from Him. And yet the Christian  community is increasingly blind to this. Moses' frequent references to the way  in which the Exodus had separated Israel from Egypt show the same spirit (Dt.  13:5; 15:15; 16:12); as our Lord in his time of dying was so strongly aware of  the way in which he was redeeming us from this present evil world.  
Deu 13:7 of the gods of the peoples who are around you, near to you or far 
	  off from you, from the one end of the land to the other end of the land-
	  
	  In Josh. 12:1,7 we meet “the kings of the 
	  earth”, i.e. of the land, and this must surely be the basis of how we are 
	  to understand the references to “the kings of the earth” in Revelation. 
	  Dt. 13:7 defines “the peoples which are round about you” [Israel] as being 
	  “from the one end of the earth even unto the other end of the earth” (RV). 
	  Those peoples which bordered with the Israelites were “the earth” /
	  eretz. 
Deu 13:8 you must not consent to him nor listen to him. Neither 
	  shall your eye pity him, neither shall you spare, neither shall you 
	  conceal him- 
	  These words are quoted in Jer. 13:14 of how God would not pity nor 
	  spare an apostate Israel. They were being asked to adopt His perspective. 
	  Deu 13:9 but you must surely kill him. Your hand shall be first on him to 
	  put him to death, and afterwards the hand of all the people-
	  There is stress upon close family members were to be the first to 
	  slay apostate members whose apostacy they had reported (Dt. 13:9; 17:7). 
	  They were being taught that they had to love God far more than family, and 
	  the Lord Jesus continued this teaching (Mt. 10:37).  
	  Deu 13:10 You must stone him to death with stones because he has sought to 
	  draw you away from Yahweh your God who brought you out of the land of 
	  Egypt, out of the house of bondage- 
	  The use of stoning (Dt. 13:10; 17:5; 21:21; 22:21,24) was to show 
	  their connection with the death of the apostate. It was to also make them 
	  realize that any attempt to deny the saving work of God in bringing them 
	  out of Egypt, or attempt to reverse it by returning them to bondage, was 
	  worthy of death (Dt. 13:10). We note that false teaching, enticing others 
	  to sin, is seen as the most serious kind of sin. The New Testament 
	  teaching about church discipline takes a similar approach; moral weakness 
	  of individuals was tolerated, although criticized; but those teaching such 
	  behaviour were condemned. Stoning resulted in the covering of the body 
	  with the dust of the earth, as if recognizing that the death being brought 
	  about was also to be the fate of all under the curse in Eden.   
	  Deu 13:11 All Israel shall hear, and fear, and shall not do any more such 
	  wickedness as this is in the midst of you- 
	  The group involvement was intended to teach others that such apostacy 
	  from Yahweh was unacceptable. We recall a similar judgment of Ananias and 
	  Sapphira in the New Testament, which lead to "fear" within the church- and 
	  then straight after that we have a notice that the church yet again 
	  experienced a growth spurt.  
	  Deu 13:12 If you hear concerning one of your cities which Yahweh your God 
	  gives you to dwell there saying- 
	  Like Paul in his time of dying, Moses in Deuteronomy saw the importance 
	  of obedience, the harder side of God; yet he also saw in real depth the 
	  surpassing love of God, and the grace that was to come, beyond Law. This 
	  appreciation reflected Moses' mature grasp of the Name / characteristics 
	  of God. He uses the name "Yahweh" in Deuteronomy over 530 times, often 
	  with some possessive adjective, e.g. "Yahweh thy God" [AV- i.e. you 
	  singular], or "Yahweh our God". He saw the personal relationship between a 
	  man and his God. Jacob reached a like realization at his peak. 
	  Deu 13:13 Certain bad men have gone out from the midst of you and have 
	  drawn away the inhabitants of their city, saying Let us go and serve other 
	  gods, which you have not known- 
	  As discussed on :10, the worst level of sin is when people turn 
	  others away from God to idolatry. The gods "which you have not known" 
	  means effectively 'With whom you cannot have relationship'. For this is 
	  the Hebrew idea of 'knowing'. The idea is not that anything new must be 
	  wrong just because they are new. Yahweh was characterized above all as the 
	  God who thirsts for personal relationship with His people. 
	  Deu 13:14 then you shall inquire and make search and ask diligently. 
	  Behold, if it is true and certain that such abomination is done in the 
	  midst of you- 
	  Allegations of misbehaviour or wrong teaching within the family of 
	  God must be taken seriously and not pushed under the carpet. But they 
	  aren’t to be acted upon without a very careful investigation, during which 
	  the love which believes and hopes all things is paramount. This passage 
	  cannot be used as a reason to divide from those who have a slightly 
	  different Biblical interpretation of something than we do, whilst 
	  believing in and worshipping the same Lord. The situation envisaged is if 
	  someone were seeking to draw Yahweh’s people away to a totally different 
	  god (:13).
Deu 13:15 you must surely strike the inhabitants of that city with the 
	  edge of the sword, destroying it utterly and all that is therein and its 
	  livestock, with the edge of the sword- 
	  Striking a city with the edge of the sword and completely destroying 
	  all life within it was what Israel did to the cities of Canaan (Josh. 
	  10:32 etc.). But the phrase is that of Dt. 13:15, about what should be 
	  done to an apostate Israelite city who turned to idolatry. This explains 
	  why the account of Joshua's campaigns list cities like Libnah and Lachish, 
	  against which the Assyrians "encamped" and fought against them (2 Chron. 
	  32:1; Is. 37:8 = Josh. 10:31). Israel were judging the Canaanite cities 
	  for their idolatry; the fact they committed the same meant that they were 
	  more than hypocritical. They had done that which they had judged. And they 
	  thereby become a warning for us. 
	  Deu 13:16 You shall gather all its spoil into the midst of its street and 
	  shall burn with fire the city and all its spoil, everything, to Yahweh 
	  your God, and it shall be a heap forever. It shall not be built again-
	  
	  The absolute destruction of everything in the apostate city meant 
	  that there was no possibility of personal gain for those judging it. This 
	  meant that the motivation in considering an accusation of apostacy would 
	  be treated without any temptation to consider personal benefit if the city 
	  were indeed judged apostate. 
	  Deu 13:17 Nothing of the devoted thing must cling to your hand, that 
	  Yahweh may turn from the fierceness of His anger and show you mercy and 
	  have compassion on you- 
	  Those who wanted to devote themselves to other gods ended up devoted 
	  to Yahweh in destruction. There is a powerful logic to devotion. The 
	  reasoning seems to be that the false teaching of the city would have 
	  spread, and all Israel would have been affected by it- and so God's fierce 
	  anger would have come upon them. It is therefore foolish to assume that 
	  wrong teaching will not spread; it is attractive by its nature. There is a 
	  strong teaching throughout the Bible about shutting down false teaching, 
	  whilst having an open attitude to sinners and misbelievers and those who 
	  misunderstand within the congregation. 
And multiply you, as He has sworn to your fathers-
	  The entire promises to Abraham and the fathers depended for their 
	  realization upon human obedience: “Hearken to these judgments, and keep, 
	  and do them, that the Lord your God shall keep with you the covenant 
	  and the mercy which He sware unto your fathers” (Dt. 7:12). That covenant 
	  was initially given in terms which omitted direct reference to any 
	  conditions for fulfilment. But it would be ‘kept’ by God if His people 
	  ‘kept’ His ways. The promises that God would multiply the seed of Abraham 
	  were conditional also; if Israel separated themselves from the 
	  peoples of the land, then  He would “multiply you, as He has 
	  sworn unto your fathers” (Dt. 13:17). 
      
	  Deu 13:18 when you listen to the voice of Yahweh your God, to keep all His 
	  commandments which I command you this day, to do that which is right in 
	  the eyes of Yahweh your God-
	  On one hand, the promises to Abraham and the fathers depended for 
	  their realization upon human obedience; even though on the other hand, the 
	  covenant of Gen. 15 appears to be a unilateral expression of God’s grace 
	  and assurance to His people. “If you listen to these ordinances and keep 
	  and do them, Yahweh your God will keep with you the covenant and the 
	  loving kindness which He swore to your fathers” (Dt. 7:12). That covenant 
	  was initially given in terms which omitted direct reference to any 
	  conditions for fulfilment. But it would be ‘kept’ by God if His people 
	  ‘kept’ His ways. The promises that God would multiply the seed of Abraham 
	  were conditional also; if Israel separated themselves from the 
	  peoples of the land and were obedient, then He would “multiply 
	  you, as He has sworn unto your fathers” (Dt. 13:17,18). The strength of 
	  God’s grace also makes some of His promises ‘conditional’ in a different 
	  sense; thus He had promised Reuben and Manasseh that they could return to 
	  their possessions only when the others had possessed the land (Dt. 3:20). 
	  This condition never happened- yet they were allowed to return. And our 
	  very salvation from death and the consequences of sin is in a sense 
	  another example of this kind of thing.
