TSK · Deuteronomy 4:42

you must then designate some towns as towns of refuge for you, to which a person who has killed someone unintentionally may flee.

Laws Concerning Manslaughter When the LORD your God destroys the nations whose land he is about to give you and you dispossess them and settle in their cities and houses,

so that we who have found refuge in him may find strong encouragement to hold fast to the hope set before us through two unchangeable things, since it is impossible for God to lie.
