Deuteronomy 19:10-12

Revised Standard Version

¹⁰ lest innocent blood be shed in your land which the Lord your God gives you for an inheritance, and so the guilt of bloodshed be upon you.

¹¹ “But if any man hates his neighbor, and lies in wait for him, and attacks him, and wounds him mortally so that he dies, and the man flees into one of these cities, ¹² then the elders of his city shall send and fetch him from there, and hand him over to the avenger of blood, so that he may die.
