Matthew 10:5 - Ellicott's Commentary On The Whole Bible

Go not into the way of the Gentiles. — The emphatic limitation seems at first sight at variance with the language which had spoken of those who should come from east and west to sit down with Abraham and Isaac and Jacob in the kingdom of God, and with the fact that our Lord had already taken His disciples into a city of Samaria, and told them that there also there were fields white for the harvest (John 4:35). We must remember, however, (1) that the limitation was confined to the mission on which they were now sent; (2) that it did but recognise a divine order, the priority of Israel in God’s dealing with mankind, “to the Jew first, and also to the Gentile;” and (3) that the disciples themselves were as yet unfitted to enter on a work which required wider thoughts and hopes than they had yet attained. It was necessary that they should learn to share their Master’s pity for the lost sheep of the house of Israel before they could enter into His yearnings after the sheep that were “not of this fold” (John 10:16).
