The devil was certain he had Jesus.
He had him “alone” in the wilderness and Jesus was hungry—very hungry. All the devil had to do was convince Jesus to trust him instead of God.
With the second of a series of three tests or temptations the devil asks Jesus to jump off the highest point of the temple because angels will catch him. He supports this by quoting Scripture. Specifically he quotes Psalm 91:11-12, which says, “He will command his angels concerning you, and they will lift you up in their hands, so that you will not strike your foot against a stone.” The devil “knows” Scripture and he’s using it with the Word incarnate. It’s really an amazing scene within the story of Jesus’ life.
