Deuteronomy 4:40-42

New Catholic Bible

⁴⁰ You shall obey his statutes and the commandments that I give you today, so that all may go well with you and your children after you, and that you may live long in the land that the Lord, your God, has given you for all time.

⁴¹ Cities of Refuge. Then Moses set aside three cities on the east of the Jordan ⁴² to which anyone who unintentionally killed another person with whom he had not previously been at enmity might flee. He could flee to one of these cities and save his life.
