Joshua 20:4-6

Amplified Bible, Classic Edition

⁴ He who flees to one of those cities shall stand at the entrance of the gate of the city and explain his case to the elders of that city; they shall receive him to [the protection of] that city and give him a place to dwell among them.

⁵ If the avenger of blood pursues him, they shall not deliver the slayer into his hand, because he killed his neighbor unintentionally, having had no hatred for him previously.

⁶ And he shall dwell in that city until he has been tried before the congregation and until the death of him who is the high priest in those days. Then the slayer shall return to his own city from which he fled and to his own house.
