Numbers 35:32
And ye shall take no satisfaction for him that is fled to the city of his refuge, that he should come again to dwell in the land, until the death of the priest.
Moreover, ye shall take no satisfaction for him that is fled to the city of his refuge,.... Though for killing a man unawares:
that he should come again to dwell in the land, until the death of the priest; the high priest; such a man's liberty was not to be purchased with money, nor even his life to be bought off, should he be taken without his city; a great ransom could not deliver him from the avenger, because he was guilty of this law, which so wisely and mercifully provided for him; and consequently guilty also of great ingratitude to God, as well as of a breach of his law, and of disrespect to his high priest, under whom he was protected.
