“When it was evening,
With the twelve.”
Καὶ ὀψίας γενομένης ἔρχεται μετὰ τῶν δώδεκα.
This is similar to Matthew, chapter 26:20, and Luke, chapter 22:14. Mark said that when it was evening or when evening arrived (Καὶ ὀψίας γενομένης), Jesus came (ἔρχεται) with the 12 apostles (μετὰ τῶν δώδεκα). Jesus and his 12 apostles were ready to celebrate the Passover in this large upper room in the city of Jerusalem.
