“As they were leaving Jericho,
A large crowd followed him.”
Καὶ ἐκπορευομένων αὐτῶν ἀπὸ Ἱερειχὼ ἠκολούθησεν αὐτῷ ὄχλος πολύς.
Both Mark, chapter 10:46, and Luke, chapter 18:35, have something similar, but with some differences. Luke has Jesus entering Jericho, not leaving it. Matthew has Jesus and his apostles or disciples leaving Jericho (Καὶ ἐκπορευομένων αὐτῶν ἀπὸ Ἱερειχὼ). As usual a large crowd followed him (ἠκολούθησεν αὐτῷ ὄχλος πολύς). Jericho was 15 miles east of Jerusalem and about 8 miles north of the Dead Sea. Jesus was getting closer to Jerusalem, but not quite there.
