Beerah his son, whom Tilgath-pilneser king of Assyria carried away into exile; he was a leader of the tribe of Reuben.

So the God of Israel stirred up the spirit of Pul, king of Assyria, [that is,] the spirit of Tilgath-pilneser king of Assyria, and he carried them away into exile—the Reubenites, the Gadites, and the half-tribe of Manasseh—and brought them to Halah, Habor, Hara, and the river Gozan, [where they remain] to this day.

So Tilgath-pilneser king of Assyria came against him and harassed him instead of strengthening and supporting him.
