Deuteronomy 19:2-4

Expanded Bible

² Then ·choose [set apart; separate] three cities in the middle of the land the Lord your God is giving you as your ·own [possession]. ³ ·Build roads to these cities [or Work out the distances], and divide the land the Lord is giving you into three parts so that someone who kills another person may run to ·these cities [^Lthere].

⁴ This is the rule for someone who kills another person and runs to one of these cities in order to save his life [Ex. 21:13–14; Num. 35:6–34; Josh. 20]. But the person must have killed a neighbor ·without meaning to [accidentally; unintentionally], not out of hatred.
