Psalm 91 Feb. 21  1He who dwells in the secret place of the Most High will rest in the shadow of the Almighty. 2I will say of Yahweh, He is my refuge and my fortress; my God, in whom I trust. 3For He will deliver you from the snare of the fowler, and from the deadly plague. 4He will cover you with His feathers, beneath His wings you will take refuge; His faithfulness is your shield and rampart. 5You shall not be afraid of the terror by night, nor of the arrow that flies by day; 6nor of the plagues that stalks in darkness, nor of the destruction that wastes at noonday. 7A thousand may fall at your side, and ten thousand at your right hand; but it will not come near you. 8You will only look with your eyes and see the recompense of the wicked. 9Because you have made Yahweh your refuge and the Most High your dwelling place, 10no evil shall happen to you, neither shall any plague come near your dwelling. 11For He will put His angels in charge of you, to guard you in all your ways; 12they will bear you up in their hands, so that you won’t dash your foot against a stone. 13You will tread on the lion and cobra, you will trample the young lion and the serpent underfoot. 14Because he has set His love on Me, therefore I will deliver him. I will set him on high, because he has known My name. 15He will call on Me and I will answer him; I will be with him in trouble, I will deliver him and honour him. 16I will satisfy him with long life, and show him My salvation.   

Commentary

91:1 This Psalm is connected with Ps. 90, and appears to also be part of that prayer of Moses. It’s especially addressed to Joshua, who during the wilderness journey lived in the tabernacle (Ex. 33:11), and was one of the few who survived the judgment of the unfaithful generation dying in the wilderness. The situation in :3-7 describes how one by one, that generation died in the wilderness, but Joshua was preserved because he had believed that Israel could inherit the promised land.
91:11,12 Jesus was tempted to misinterpret these words as meaning that whatever He did from whatever motives, God would somehow preserve Him (Mt. 4:6). Temptation is very subtle; for the believer, misusing God’s words in order to justify whatever we feel like doing in the heat of a moment is a common form of temptation. This Psalm was encouragement to Joshua (see on :1), the Hebrew form of ‘Jesus’; so it’s understandable that Jesus would’ve been especially aware of these words.
91:14 Joshua (see on :1) was preserved because he believed that God would really give His people the promised Kingdom; but this faith is here described as loving God and knowing His Name. Joshua wanted Israel to inherit the Kingdom because he loved God, not because he wanted any personal benefit for himself. We see here how the New Testament triad of faith, hope and love were all interwoven within the character of Joshua.
