If the avenger of blood pursues him, then they must not deliver up the killer into his hand, because he struck down his neighbor unintentionally and did not hate him previously. Bible see other translations

“unintentionally.” Literally, “without knowledge” (cp. Josh. 20:3).

“hate him previously.” A Hebrew idiom: more literally, “yesterday or three,” but the meaning is “previously,” “before,” “in times past.”
