Matthew 4:7

4:7 Jesus said to him, “Once again it is written: ‘You are not to put the Lord your God to the test.’” ¹ 

Matthew 4:10

4:10 Then Jesus said to him, “Go away, ²  Satan! For it is written: ‘You are to worship the Lord your God and serve only him.’” ³ 

[4:7]  ¹ sn A quotation from Deut 6:16.

[4:10]  ² tc The majority of later witnesses (C² D L Z 33 Ï) have “behind me” (ὀπίσω μου; opisw mou) after “Go away.” But since this is the wording in Matt 16:23, where the text is certain, scribes most likely added the words here to conform to the later passage. Further, the shorter reading has superior support (א B C*^vid K P W Δ 0233 Ë^1,13 565 579* 700 al). Thus, both externally and internally, the shorter reading is strongly preferred.

[4:10]  ³ sn A quotation from Deut 6:13. The word “only” is an interpretive expansion not found in either the Hebrew or Greek (LXX) text of the OT.
