“The twelve apostles
To be distressed.
They said to Jesus.
One after another.
ἤρξαντο λυπεῖσθαι καὶ λέγειν αὐτῷ εἷς κατὰ εἷς Μήτι ἐγώ;
This is similar to Matthew, chapter 26:22, and something similar to Luke, chapter 22:23, and John, chapter 13:22. The 12 apostles began to be greatly distressed or pained (ἤρξαντο λυπεῖσθαι) on hearing that one of them was going to betray Jesus. They said to Jesus, one after another (καὶ λέγειν αὐτῷ εἷς κατὰ εἷς) that it was surely not any of them. Each one declared in the first person singular “Surely! Not I! (Μήτι ἐγώ)!” Mark did not have them say “Lord!” as Matthew indicated.
