Numbers 35:13-15

New Century Version

¹³ The six cities you give will be cities of safety. ¹⁴ Give three cities east of the Jordan River and three cities in Canaan as cities of safety. ¹⁵ These six cities will be places of safety for citizens of Israel, as well as for foreigners and other people living with you. Any of these people who accidentally kills someone may run to one of these cities.
