Deuteronomy 19:2-3
2
Thou shalt separate three cities for thee in the midst of thy land, which the LORD thy God giveth thee to possess it.
3
Thou shalt prepare thee a way, and divide the coasts of thy land, which the LORD thy God giveth thee to inherit, into three parts, that every slayer may flee thither.
