I will give one tribe to thy son - There were left to Rehoboam the tribes of Judah, Benjamin, and Levi (2Ch 11:12, 2Ch 11:13); and multitudes of Israelites, who, after the schism of the kingdom, established their residence within the territory of Judah to enjoy the privileges of the true religion (1Ki 12:17). These are all reckoned as one tribe.
