Charles Ellicott Commentary 1 Chronicles 5:4-6

"The sons of Joel: Shemaiah his son, Gog his son, Shimei his son, Micah his son, Reaiah his son, Baal his son, Beerah his son, whom Tilgath-pilneser king of Assyria carried away captive: he was prince of the Reubenites." — 1 Chronicles 5:4-6 (ASV)

The sons of Joel. —The connection of this leading house with one of the four sons just mentioned, is implied but not stated. The line of Joel is traced through seven generations to Beerah, who was transported to Assyria by Tiglath Pileser II, 734 B.C., in the reign of Pekah, king of Israel. Supposing there are no gaps in the series, Joel flourished 280 years (7 x 40) before that date; that is, about 1014 B.C., under David and Solomon.
