These twelve Jesus sent forth, and commanded them, saying,
Go not into the way of the Gentiles, and into any city of the Samaritans enter you not:
All Commentaries on Matthew 10:5 Go To Matthew 10
Hilary of Poitiers
AD 368
They are warned to avoid the ways of the Gentiles, not because they were never going to be sent for the salvation of the Gentiles, but because they were to avoid the works and lifestyle of the unenlightened Gentiles. They were forbidden to enter the towns of the Samaritans. Yet, did he not cure the Samaritan woman? They were warned, moreover, not to go into the assemblies of heretics. For heterodoxy does not differ at all from unenlightenment. Therefore they were being sent to the lost sheep of the house of Israel, who raged against him with the tongues and jaws of wolves and vipers. At any rate, the law was due to receive the special benefit of the gospel. The less excuse Israel had for its ungodly behavior, the more zeal it might have in heeding the warning.
