“I will say to the LORD, “My refuge and my fortress, my God, in whom I trust.” For He will deliver you from the snare of the fowler and from the deadly pestilence. He will cover you with his pinions, and under his wings, you will find refuge; his faithfulness is a shield and buckler. You will not fear the terror of the night, nor the arrow that flies by day, nor the pestilence that stalks in darkness, nor the destruction that wastes at noonday ... Because you have made the LORD your dwelling place – the Most High, who is my refuge – no evil shall be allowed to befall you, no plague come near your tent. For he will command his angels concerning you to guard you in all your ways. ” Psalms 91:1-6, 9-11

Now, this magnificent poem does not necessarily mean that the faithful – those who dwell “in the shelter of the Most High”– will not get the pestilence or suffer the other afflictions mentioned. 

Satan used this Psalm in his temptation of Jesus (Matthew 4:5-7), trying to get him to invoke its promise that angels “will bear you up” by throwing himself off from the pinnacle of the Temple.  But such an interpretation, Jesus points out, would be to put God to the test, violating Deuteronomy 6:16.

But those who trust God as their refuge will be delivered from the evil of the pestilence and from fear of it.

Look at these promises of God to David. They are yours if you hold fast to God in love.

“Because He holds fast to me in love, I will deliver him; I will protect Him because he knows my name.
When he calls to me, I will answer him; I will be with him in trouble; I will rescue him and honor him.
With long life, I will satisfy him and show him my salvation.” Psalms 91:14-16
