'Stranger' in the Bible

My son, if you have become surety for your neighbor,Have given a pledge for a stranger,

He who is guarantor for a stranger will surely suffer for it,But he who hates being a guarantor is secure.

The heart knows its own bitterness,And a stranger does not share its joy.

Take his garment when he becomes surety for a stranger;And for foreigners, hold him in pledge.

Let another praise you, and not your own mouth;A stranger, and not your own lips.

Take his garment when he becomes surety for a stranger;And for an adulterous woman hold him in pledge.
