'Stranger' in the Bible

if ye oppress not the stranger, the fatherless, and the widow, and shed no innocent blood in this place, neither walk after other gods to your hurt;

Thou hope of Israel, its Saviour in the time of trouble, why wilt thou be as a stranger in the land, and as a traveller that turneth aside to stay a night?

Thus saith Jehovah: Execute judgment and righteousness, and deliver the spoiled out of the hand of the oppressor; and do no wrong, do no violence to the stranger, the fatherless, or the widow, and shed not innocent blood in this place.
