Deuteronomy 15:2

15:2 This is the nature of the cancellation: Every creditor must remit what he has loaned to another person; he must not force payment from his fellow Israelite, for it is to be recognized as “the Lord’s cancellation of debts.”

Deuteronomy 19:5

19:5 Suppose he goes with someone else to the forest to cut wood and when he raises the ax to cut the tree, the ax head flies loose from the handle and strikes his fellow worker so hard that he dies. The person responsible may then flee to one of these cities to save himself.
