1 Chronicles 5:17

The very form of the language of this verse would indicate that two genealogies are intended. This quite tallies with the fact that there were two chronicles , one for each division of the nation, i.e. "the chronicles of the kings of Judah" ( 2 Kings 15:6 ) and "the chronicles of the kings of Israel" ( 2 Kings 15:11 ), in which same chapter both Jeroboam ( II .) of Israel and Jotham of Judah are spoken of, the latter beginning to reign in Judah some twenty years (the exact chronology is very confused here) after the death of the former. Although presumably it would be an object of closer interest with Israel than with Judah to effect the registration of the Gadite genealogy, yet it was most just that Judah should do so as well. This would both vindicate Judah's own right place and be a happy omen of the continued predominance of her position compared with that of Israel. Independently of the question of effecting the actual registration, however, it is quite possible that, so long as history ran by the side of history. Israel would gather and keep all it could of Judah, and Judah all it could of Israel.
