'Foreigner' in the Bible

In you have they set light by father and mother; in the midst of you have they dealt by oppression with the foreigner; in you have they wronged the fatherless and the widow.

The people of the land have used oppression, and exercised robbery; yes, they have troubled the poor and needy, and have oppressed the foreigner wrongfully.

Thus says the Lord Yahweh, No foreigner, uncircumcised in heart and uncircumcised in flesh, shall enter into my sanctuary, of any foreigners who are among the children of Israel.
