But as for the children of Israel that dwelt in the cities of Judah, Rehoboam reigned over them.
When the kingdom was rent in two, Rehoboam's rule did not end but continued over those Israelites who were dwelling in the cities of Judah. The southern kingdom that remained under him was constituted by the two tribes of Judah and Benjamin, joined together as Judah. The other ten tribes in the north were formed into a separate kingdom of Israel under Jeroboam.
