“It is written.
‘God will command
He will protect you.’”
γέγραπται γὰρ ὅτι τοῖς ἀγγέλοις αὐτοῦ ἐντελεῖται περὶ σοῦ τοῦ διαφυλάξαι σε,
Although Matthew, chapter 4:6, has this as the second temptation, Luke has this as the last temptation. However, the wording is the almost the same, indicating a shared common source. Interesting enough, the devil cited Psalm 91:11-12, so that even the devil can quote scripture. Luke indicated that this devil said that it was written (γέγραπται γὰρ) that God will command or give orders to his angels (ὅτι τοῖς ἀγγέλοις αὐτοῦ ἐντελεῖται) concerning him (περὶ σοῦ), so that he would guard or protect him (τοῦ διαφυλάξαι σε). The devil, said that God would command these angels to protect or guard him so that Jesus had nothing to worry about.
