1 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 Ë1,13 565 579* 700 al). Thus, both externally and internally, the shorter reading is strongly preferred.
2 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.
3 sn The double use of the vocative is normally used in situations of high emotion or emphasis. Even an emphatic confession without action means little.
