The 91st Psalm is one that teaches us about the deliverance of God. It paints a picture of God as a protector like a bird covering its young. It reminds us that even when all seems to be falling apart around us, God is there watching out. It’s a passage that encourages us to take refuge in God and to trust in him.
So it seems strange is the one that Satan quotes to tempt Jesus.
Then the devil took Him into the holy city and had Him stand on the pinnacle of the temple, and said to Him, "If You are the Son of God, throw Yourself down; for it is written, 'HE WILL COMMAND HIS ANGELS CONCERNING YOU'; and 'ON their HANDS THEY WILL BEAR YOU UP, SO THAT YOU WILL NOT STRIKE YOUR FOOT AGAINST A STONE.'"
Satan knows Scripture. He will twist it to make us think his lies are legitimate. The psalm encourages us to rest in God not test him. Yet the Devil tries to paint the message that way. It a technique that he and his lickspittles still use today
Peter says as much in 2nd Peter 3:16. False teacher distorts and twists all the scriptures to make it say something it never was saying. That is why we must be diligent to make sure we are trusting in the promises of God not the skewed perception from men.
Lots of folks will quote scripture. We have to make sure they are using it correctly.
