Deuteronomy 4:42
that the manslayer might flee there, who kills his neighbor unawares, and did not hate him in time past, and that fleeing to one of these cities he might live:
Numbers 35:6
And of the cities which ye shall give to the Levites, there shall be the six cities of refuge, which ye shall give for the manslayer to flee to. And besides them ye shall give forty-two cities.
Numbers 35:11-12
then ye shall appoint cities to be cities of refuge for you, that the manslayer who kills any person unwittingly may flee there.
Numbers 35:15-28
For the sons of Israel, and for the stranger and for the sojourner among them, these six cities shall be for refuge, that everyone who kills any person unwittingly may flee there.
Deuteronomy 19:1-10
When LORD thy God shall cut off the nations, whose land LORD thy God gives thee, and thou succeed them, and dwell in their cities, and in their houses,
Hebrews 6:18
So that by two immutable events, in which it is impossible for God to lie, we may have strong encouragement, having fled for refuge to seize the hope being openly displayed.
