Gentiles (i.e., non‑Jewish people of “the nations,” a.k.a. Goyim) came to embrace the message of Messiah Jesus from their Jewish neighbors in such high numbers that faith in Jesus slowly came to be known as an entirely Gentile thing. But Jesus himself did not personally embrace the Gentiles during his ministry. In fact, he largely avoided them.

>When Jesus prescribes to his followers how to deal with a non-repentant person who has committed a significant sin against the community, he says, “Treat them like a Gentile”—in other words, don’t interact with them (Matthew 18:17).

>He also uses them as negative examples in his teaching: “If you greet only your brothers, what more are you doing than others? Do not even the Gentiles do the same?” (Matthew 5:47, cf. Matthew 6:7).

>He uses Gentile rulers as an example of unrighteous leadership (Matthew 20:25–29).

>And in his encounter with the Gentile Canaanite woman, it is clear that he accepts entirely what the Tanakh teaches about not making covenants with people of the idolatrous Gentile nations (Exodus 34:12; Deuteronomy 7:1–8; Joshua 23:11–13; Ezra 10:1–5; et al).
