'Foreigners' in the Bible

It is written in the Law, “By men of strange tongues and by the lips of foreigners I will speak to this people, and not even then will they listen to Me,” says the Lord.

Now an overseer must be blameless and beyond reproach, the husband of one wife, self-controlled, sensible, respectable, hospitable, able to teach,

And he must be hospitable [to believers, as well as strangers], a lover of what is good, sensible (upright), fair, devout, self-disciplined [above reproach—whether in public or in private].

Be hospitable to one another without complaint.
