'Stranger' in the Bible

My child, if you have made a pledge for your neighbor, and have become a guarantor for a stranger,

The one who puts up security for a stranger will surely have trouble, but whoever avoids shaking hands will be secure.

Take a man's garment when he has given security for a stranger, and when he gives surety for strangers, hold him in pledge.

Take a man's garment when he has given security for a stranger, and when he gives surety for a stranger, hold him in pledge.
