'Stranger' in the Bible

My son, if you have become collateral for your neighbor, if you have struck your hands in pledge for a stranger;

He who is collateral for a stranger will suffer for it, but he who refuses pledges of collateral is secure.

The heart knows its own bitterness and joy; he will not share these with a stranger.

Take the garment of one who puts up collateral for a stranger; and hold him in pledge for a wayward woman.

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

Take his garment when he puts up collateral for a stranger. Hold it for a wayward woman!
