“Peter said to Jesus.
‘Though they all
Because of you,
I will never
ἀποκριθεὶς δὲ ὁ Πέτρος εἶπεν αὐτῷ Εἰ πάντες σκανδαλισθήσονται ἐν σοί, ἐγὼ οὐδέποτε σκανδαλισθήσομαι.
This is almost word for word in Mark, chapter 14:29, and similar in Luke, chapter 22:31-33, and in John, chapter 13:36-37, where there is a longer discussion with Peter. Here this is a short succinct discussion. Peter answered Jesus saying (ἀποκριθεὶς δὲ ὁ Πέτρος εἶπεν αὐτῷ) that even though all the disciples might stumble and desert Jesus (Εἰ πάντες σκανδαλισθήσονται ἐν σοί), he would never stumble or desert Jesus (ἐγὼ οὐδέποτε σκανδαλισθήσομαι). Peter seemed so self-assured of himself, that he would never leave Jesus, no matter what.
