“But Jesus

Said to them.

‘I must proclaim

The good news

Of the kingdom of God

To the other towns also.

I was sent

For this purpose.’”

ὁ δὲ εἶπεν πρὸς αὐτοὺς ὅτι Καὶ ταῖς ἑτέραις πόλεσιν εὐαγγελίσασθαί με δεῖ τὴν βασιλείαν τοῦ Θεοῦ, ὅτι ἐπὶ τοῦτο ἀπεστάλην.

Luke indicated that Jesus said to them (ὁ δὲ εἶπεν πρὸς αὐτοὺς) that it was his duty (με δεῖ) to proclaim or preach the good news (εὐαγγελίσασθαί) about the kingdom of God (τὴν βασιλείαν τοῦ Θεοῦ) to the other towns or cities also (ὅτι Καὶ ταῖς ἑτέραις πόλεσιν).  He was sent for that purpose (ὅτι ἐπὶ τοῦτο ἀπεστάλην).  There is something similar in Mark. chapter 1:37-38, but there was no explicit message about proclaiming the good news of the kingdom of God.  Mark simply recounted that Jesus said to his followers that they were going into the nearby neighboring towns or villages.  Thus, he could proclaim or preach his unspecified message there.  That was what he came to do, since it was time to get to work.  Jesus had to move on to the other nearby towns and villages to proclaim his message.
