“Jesus answered him.
‘It is written.
Serve only him!’”
καὶ ἀποκριθεὶς ὁ Ἰησοῦς εἶπεν αὐτῷ Γέγραπται Προσκυνήσεις Κύριον τὸν Θεόν σου καὶ αὐτῷ μόνῳ λατρεύσεις.
Just like in Matthew, chapter 4:10, the wording is nearly the same, indicating perhaps a common Q source. Once again, Jesus had a very direct response to the devil (καὶ ἀποκριθεὶς ὁ Ἰησοῦς εἶπεν αὐτῷ). He referred to another scriptural writing (Γέγραπται) from Deuteronomy, chapter 6:13. This was again a simple statement that you should only worship the Lord your God (Προσκυνήσεις Κύριον τὸν θεόν σου). You should serve him alone (καὶ αὐτῷ μόνῳ λατρεύσεις). In Deuteronomy, chapter 6:13, Yahweh had said they should only fear and serve Yahweh and swear by his name only. The only main difference with Matthew, is that Jesus told the devil to go away. That was not here in Luke.
