Psalm 91 shows God is determined to build a confrontation with human beings over their murderous behavior.
Here is the full statement in psalm 91, verses 1 to 16. 1 He who dwells in the secret place of the Most High shall remain stable and fixed under the shadow of the Almighty, Whose power no foe can withstand 2 I will say of the Lord, He is my Refuge and my Fortress, my God; on Him I lean and rely, and in Him I confidently trust! 3 For then He will deliver you from the snare of the fowler and from the deadly pestilence. 4 Then He will cover you with His pinions, and under His wings shall you trust and find refuge; His truth and His faithfulness are a shield and a buckler. 5 You shall not be afraid of the terror of the night, nor of the arrow that flies by day, 6 Nor of the pestilence that stalks in darkness, nor of the destruction and sudden death that surprise and lay waste at noonday. 7 A thousand may fall at your side, and ten thousand at your right hand, but it shall not come near you. 8 Only a spectator shall you be as you witness the reward of the wicked. 9 Because you have made the Lord your refuge, and the Most High your dwelling place. 10 There shall no evil befall you, nor any plague or calamity come near your tent. 11 For He will give His angels charge over you to accomplish and defend and preserve you in all your ways of obedience and service. 12 They shall bear you up on their hands, lest you dash your foot against a stone. 13 You shall tread upon the lion and adder; the young lion and the serpent shall you trample underfoot. 14 Because he has set his love upon Me, therefore will I deliver him; I will set him on high, because he knows and understands My name. 15 He shall call upon Me, and I will answer him; I will be with him in trouble, and I will deliver him and honor him. 16 With long life will I satisfy him and show him My salvation.
This is an interesting psalm that has several important aspects for a bible reader to comprehend. One of which is that the writer of this psalm is not referring to Jesus. If he was, he would capitalize a reference to him in his words.
Another important thing for a bile reader to realize is that the bible needs somebody to show up and definitively play this role. In order to do that, the bible needs a lot of other unfulfilled statements which only the person in psalm 91 can complete. When this is done, the person in psalm 91 can be identified.
