surety for thy friend
Proverbs 6:1
6:1 surety for thy friend. Here is a strong Biblical warning against agreeing to be responsible for another person’s debts. If such a person really needs and deserves help, it is better (even for that person) to give him the money needed, or to lend it (without interest) than to encourage greed and irresponsibility on his part by assuming his debts.
