<p>1:20 <i>For it is written in the book of Psalms: Let his habitation be made desolate and let no one dwell therein, and his office let another take</i> - The condemnation of Jewry for crucifying Christ in Ps. 69:25 (&quot;let <em>their</em> habitation be desolate&quot;) is quoted in the singular about Judas in Acts 1:20. What was true of Judas was also true of Israel in general; in the same way as the pronouns used about Judas merge from singular into plural in Ps. 55:13-15 (&quot;a man mine equal... let death seize upon them&quot;), as also in Ps. 109:3 cp. v.8.</p><p>Psalm 109 is a prophecy of Christ&rsquo;s betrayal and death (:8 = Acts 1:20). The satans (&ldquo;adversaries&rdquo;) of the Lord Jesus which the Psalm speaks of (:4,20,29) were the Jews, and the specific &lsquo;Satan&rsquo; of v. 6 was Judas. Psalm 55:13&ndash;15 foretells Judas&rsquo; betrayal of Jesus. It speaks of Judas in the singular, but also talk of his work as being done by a group of people &ndash; the Jews, in practice: &ldquo;It was you, a man mine equal, my guide, and mine acquaintance. We took sweet counsel together... let death seize them (plural), and let <em>them</em> go down quickly into hell&rdquo; (cp. Judas&rsquo; end). Likewise the other prophecy of Judas&rsquo; betrayal also connects him with the Jewish system: &ldquo;My own familiar friend, in whom I trusted, which did eat of my bread (cp. Jesus passing the sop to Judas), has lifted up his heel against me. But You, O Lord, be merciful unto me, and raise me up, that I may requite them&rdquo; (Ps. 41:9,10). Thus Judas is being associated with the Jews who wanted to kill Jesus, and therefore he, too, is called a Devil. Both Judas and the Jews were classic &lsquo;devils&rsquo; due to their surrender to the flesh. This is further confirmed by a look as Psalm 69. Verse 22 is quoted in Romans 11:9,10 concerning the Jews: &ldquo;Let their table become a snare before them... let their eyes be darkened&rdquo;. The passage continues in Psalm 69:25: &ldquo;Let <em>their</em> habitation be desolate; let none dwell in <em>their</em> tents&rdquo;. This is quoted in Acts 1:16,20 as referring specifically to Judas, but the pronouns are changed accordingly: &ldquo;This scripture must needs have been fulfilled, which the Holy Spirit by the mouth of David spake before concerning Judas... Let <em>his</em> singular habitation be desolate, and let no man dwell therein: and <em>his</em> bishopric let another take&rdquo;.</p><p>Ps. 109:8 is quoted in Acts 1:20 concerning Judas, suggesting that the preceding&nbsp;v.6 reveals Christ's thoughts about him: &quot;Set Thou a wicked man over him: and let satan stand at his right hand&quot;, implying that Jesus prayed for the Jewish satan to help or co-operate with Judas (which is how the idiom of standing at the right hand is used in Ps. 109:31). This is tantamount to not praying that Judas would overcome the advances of the Jews which the Lord would have been aware they were making. But he could encourage Peter that he had prayed for him to resist these advances (Lk. 22:32). The whole of Ps. 109 is a prayer requesting the punishment of Judas, asking God to confirm him in his supreme apostasy: &quot;Let his prayer become sin&quot; (Ps. 109:7). The last section of the Psalm (109:22-29) describes Christ's sufferings on the cross in language that has many connections with Ps.22 and 69; and as with them there is a sudden breakthrough at the end into looking forward to praising God &quot;among the multitude&quot; (Ps. 109:30), as there is in Ps. 22:22. This may mean that it was on the cross that the enormity of Judas' sin was fully realized by Christ, although he had previously recognized it to some degree before the cross (Jn. 19:11; Mt. 26:24).&nbsp;</p>
