Deuteronomy 4:40

Because he loved your fathers, therefore he chose their offspring after them, and brought you out with his presence, with his great power, out of Egypt;

to drive out nations from before you greater and mightier than you, to bring you in, to give you their land for an inheritance, as it is today.

Know therefore today, and take it to heart, that the LORD himself is God in heaven above and on the earth beneath. There is no one else.

Then Moses set apart three cities beyond the Jordan toward the sunrise,

that the man slayer might flee there, who kills his neighbor unintentionally and didn’t hate him in time past, and that fleeing to one of these cities he might live:

Bezer in the wilderness, in the plain country, for the Reubenites; and Ramoth in Gilead for the Gadites; and Golan in Bashan for the Manassites.
