If thou be the Son of God] See on v. 3.
cast thy self down] Satan doth not offer to throw him down, for that God would not suffer him, or because he sought to bring Christ to sin, rather then to death; whereas, if Satan had cast him down, Christ had not sinned.
for it is written] Psalms 91:11. The devil now seeks to foil Christ with his own weapons, and cites Scripture, as he had done before, v. 4.

they shall bear thee up] A metaphor taken from the manner of them that carry young children in their arms.
