'Foreign' in the Bible

Then I said, “What you are doing isn’t right. Shouldn’t you walk in the fear of our God and not invite the reproach of our foreign enemies?

When they heard the Law, they separated all those of foreign descent from Israel.

Didn’t King Solomon of Israel sin in matters like this? There was not a king like him among many nations. He was loved by his God and God made him king over all Israel, yet foreign women drew him into sin.

Why then should we hear about you doing all this terrible evil and acting unfaithfully against our God by marrying foreign women?”

So I purified them from everything foreign and assigned specific duties to each of the priests and Levites.
