Deuteronomy 19:2; Joshua 20:7

qyou shall set apart three cities for yourselves in the land that the Lord your God is giving you to possess.


So they set apart mKedesh in Galilee in the hill country of Naphtali, and nShechem in the hill country of Ephraim, and oKiriath-arba (that is, Hebron) pin the hill country of Judah.
