“Then Jesus
Said to them.
‘The cup that I drink,
You will drink.
With the baptism
With which I am baptized,
You will be baptized.”
ὁ δὲ Ἰησοῦς εἶπεν αὐτοῖς Τὸ ποτήριον ὃ ἐγὼ πίνω πίεσθε, καὶ τὸ βάπτισμα ὃ ἐγὼ βαπτίζομαι βαπτισθήσεσθε·
There is something similar to this in Matthew, chapter 20:23, but slightly different. Mark indicated that Jesus said to the two sons of Zebedee (ὁ δὲ Ἰησοῦς εἶπεν αὐτοῖς), James and John, that they would indeed drink of the suffering cup of Jesus (Τὸ ποτήριόν ὃ ἐγὼ πίνω πίεσθε). They would also undergo the baptism that he was going to suffer (καὶ τὸ βάπτισμα ὃ ἐγὼ βαπτίζομαι βαπτισθήσεσθε). Jesus warned these two important apostles that they would drink of the suffering cup and the undergo the baptism of suffering also.
