10:5 Go not into the way of the Gentiles. The Jews called all Gentiles who were not Jews.
Samaritans. The inhabitants of Samaria, a district between Judea and Galilee; descendants of a remnant of the Ten Tribes, mixed with Gentiles colonized there. They accepted the five books of Moses, but worshipped on Mount Gerizim, instead of at Jerusalem. They and the Jews had been for ages bitter enemies.
10:5 These twelve Jesus sent forth - Herein exercising his supreme authority, as God over all. None but God can give men authority to preach his word. Go not - Their commission was thus confined now, because the calling of the Gentiles was deferred till after the more plentiful effusion of the Holy Ghost on the day of pentecost. Enter not - Not to preach; but they might to buy what they wanted, John 4:9.
10:5-15 The Gentiles must not have the gospel brought them, till the Jews have refused it. This restraint on the apostles was only in their first mission. Wherever they went they must proclaim, The kingdom of heaven is at hand. They preached, to establish the faith; the kingdom, to animate the hope; of heaven, to inspire the love of heavenly things, and the contempt of earthly; which is at hand, that men may prepare for it without delay. Christ gave power to work miracles for the confirming of their doctrine. This is not necessary now that the kingdom of God is come. It showed that the intent of the doctrine they preached, was to heal sick souls, and to raise those that were dead in sin. In proclaiming the gospel of free grace for the healing and saving of men's souls, we must above all avoid the appearance of the spirit of an hireling. They are directed what to do in strange towns and cities. The servant of Christ is the ambassador of peace to whatever place he is sent. His message is even to the vilest sinners, yet it behoves him to find out the best persons in every place. It becomes us to pray heartily for all, and to conduct ourselves courteously to all. They are directed how to act as to those that refused them. The whole counsel of God must be declared, and those who will not attend to the gracious message, must be shown that their state is dangerous. This should be seriously laid to heart by all that hear the gospel, lest their privileges only serve to increase their condemnation.
