And it came to pass, when Jesus had made an end of commanding his twelve disciples, he departed thence to teach and to preach in their cities. This verse properly belongs to the preceding chapter, from which it should on no account be separated; as with that it has the strictest connection, but with this it has none.
To teach and to preach - To teach, to give private instructions to as many as came unto him; and to preach, to proclaim publicly, that the kingdom of God is at hand; two grand parts of the duty of a Gospel minister.
Their cities - The cities of the Jews.
