Devarim 19:1-3

Orthodox Jewish Bible

19 When Hashem Eloheicha hath cut off the Goyim, whose land Hashem Eloheicha giveth thee, and thou dispossess them, and dwellest in their towns, and in their batim (houses),

² Thou shalt separate shalosh arim (three towns) for thee in the midst of thy land, which Hashem Eloheicha giveth thee to possess it.

³ Thou shalt prepare yourselves roads, and divide the territory of thy land, which Hashem Eloheicha giveth thee to inherit, into three parts, that every slayer may flee there.
