'Stranger' in the Bible

My son, if thou art become surety for thy neighbor, If thou hast stricken thy hands for a stranger;

He that is surety for a stranger shall smart for it; But he that hateth suretyship is secure.

The heart knoweth its own bitterness; And a stranger doth not intermeddle with its joy.

Take his garment that is surety for a stranger; And hold him in pledge that is surety for foreigners.

Let another man praise thee, and not thine own mouth; A stranger, and not thine own lips.

Take his garment that is surety for a stranger; And hold him in pledge that is surety for a foreign woman.
