“Peter said to Jesus.
‘Even though
All become deserters,
I will not.’”
ὁ δὲ Πέτρος ἔφη αὐτῷ Εἰ καὶ πάντες σκανδαλισθήσονται, ἀλλ’ οὐκ ἐγώ.
This is almost word for word in Matthew, chapter 26:33, and similar in Luke, chapter 22:31-33, as well as in John, chapter 13:36-37, where there is a longer discussion with Peter. Here this is a short succinct discussion. Mark indicated that Peter said to Jesus (ὁ δὲ Πέτρος ἔφη αὐτῷ) that even though all the disciples and apostles might stumble and desert Jesus (Εἰ καὶ πάντες σκανδαλισθήσονται), he would not stumble or desert Jesus (ἀλλ’ οὐκ ἐγώ), not him. Peter seemed so self-assured of himself, that he would never leave Jesus, no matter what. How self-assured are you?
