In short

Gentiles here in Matthew 10:5 means not individual Gentiles, but the Gentile nations living in Gentile lands. The command to go nowhere among the Gentiles means to stay within the borders of the land of the Jews. The first word of the phrase town (polis) of the Samaritans is the Greek equivalent of the Aramaic word mediná, which can also mean a province or a territory. Jesus specifically means the area in between Judea and Galilee, which had a mixed population due to colonization (2 Kings 17:24–28).

With Gentiles here in Matthew 10:5 Jesus does not mean individual Gentiles, but rather (in contradistinction to the house of Israel) the Gentile nations living in Gentile lands. The command to go nowhere among the Gentiles means to remain within the borders of the land of the Jews.¹ The first word of the phrase town (polis) of the Samaritans is the Greek equivalent of the Aramaic word mediná, which can also refer to a province or a territory. Jesus is here specifically referring to the area located in between Judea and Galilee, which had a mixed population as a result of colonization (2 Kings 17:24–28)²
