1My son, if someone has borrowed money from a friend or a stranger, and if you have promised that you will pay the money back if that person is unable to pay back the money he borrowed,
1My son, if thou hast promised for thy friend, thou hast fastened thine hand at a stranger. (My son, if thou hast pledged yourself, or made a guarantee, for thy friend, then thou hast fastened thy hand to a stranger.)
