'Foreigner' in the Bible

Generation after generation, every male among you is to be circumcised on the eighth day after his birth, including the servant born in your house or the one purchased from a foreigner, who is not of your offspring.

Every man born in his household as well as those who had been purchased with money from a foreigner was circumcised with him.

But they replied, "Get out of the way! This man came here as a foreigner, and now he's acting like a judge! So we're going to deal more harshly with you than with them." Then they pushed hard against the man (that is, against Lot), intending to break down the door.

Therefore swear an oath here by God that you won't deal falsely with me, my sons, or my descendants. Just as I've dealt graciously with you, won't you do so with me and with the land in which you live as a foreigner?"

After this, Abraham resided as a foreigner in Philistine territory for a long period of time.
