2 Chronicles 11:13

The priests and Levites resorted to him out of all their coasts So the tribe of Levi was added to the tribe of Judah; though not the cities, in general, wherein they dwelt, which they were forced to leave when they would not conform to the idolatrous worship which Jeroboam had set up. The tribe of Simeon, likewise, was so intermixed with Judah, that, in all probability, many cities thereof, if not all, became one body with it, which made Judah a very powerful kingdom.
