'Stranger' in the Bible

In thee have they made light of father and mother; in the midst of thee have they dealt by oppression with the stranger; in thee have they vexed the fatherless and the widow.

The people of the land use oppression and practise robbery; and they vex the poor and needy, and oppress the stranger wrongfully.

Thus saith the Lord Jehovah: No stranger, uncircumcised in heart and uncircumcised in flesh, shall enter into my sanctuary, of any stranger that is among the children of Israel.

And it shall come to pass that in the tribe in which the stranger sojourneth, there shall ye give him his inheritance, saith the Lord Jehovah.
