“Jesus
Went throughout all Galilee.
He was teaching
In their synagogues.
He was proclaiming
The good news
Of the kingdom.
He was healing
Every disease
And every sickness
Among the people.
Καὶ περιῆγεν ἐν ὅλῃ τῇ Γαλιλαίᾳ, διδάσκων ἐν ταῖς συναγωγαῖς αὐτῶν καὶ κηρύσσων τὸ εὐαγγέλιον τῆς βασιλείας καὶ θεραπεύων πᾶσαν νόσον καὶ πᾶσαν μαλακίαν ἐν τῷ λαῷ.
This summary statement seems to be unique to Matthew, but not inconsistent with the other gospel stories. There is something similar in Mark 1:39 and Luke 4:14, about Jesus being in Galilee. Matthew implied that Jesus went all over Galilee (Καὶ περιῆγεν ἐν ὅλῃ τῇ Γαλιλαίᾳ), not just around the Sea of Galilee. He was teaching in their synagogues (διδάσκων ἐν ταῖς συναγωγαῖς αὐτῶν). However, synagogue might mean a group or assembly of Jewish people rather than a building, since some places may not have been able to afford a building. Matthew said that Jesus was proclaiming the good news or the gospel about the kingdom (καὶ κηρύσσων τὸ εὐαγγέλιον τῆς βασιλείας), without saying whether it was the kingdom of God, the kingdom of heaven, or even an earthly kingdom. Jesus was like a faith healer, also healing all diseases and curing people of all their sicknesses and illnesses (καὶ θεραπεύων πᾶσαν νόσον καὶ πᾶσαν μαλακίαν). In other words, he was this itinerant preacher healing people (ἐν τῷ λαῷ).
