I Chronicles 5:3

The sons, I say, of Reuben the firstborn of Israel, were, Hanoch, and Pallu, Hezron, and Carmi. As in Gen 46:9. . 1 Chronicles 5:4 ch1 5:4 ch1 5:4 ch1 5:4The sons of Joel,.... Who was either the son of Carmi last mentioned, or rather of Hanoch, Reuben's firstborn, since the descendants of him were the princes of the tribe: his posterity in succession were, Shemaiah, Cog, Shimei, Micah, Reaia, Baal, Beerah; of whom we know no more than their names, and by these the descent is carried down to the captivity by Tiglathpileser, as follows.

This chapter gives us some account of the two tribes and a half that were seated on the other side Jordan. I. Of Reuben (Ch1 5:1-10). II. Of Gad (Ch1 5:11-17). III. Of the half-tribe of Manasseh (Ch1 5:23, Ch1 5:24). IV. Concerning all three acting in conjunction we are told, 1. How they conquered the Hagarites (Ch1 5:18-22). 2. How they were, at length, themselves conquered, and made captives, by the king of Assyria, because they had forsaken God (Ch1 5:25, Ch1 5:26).

5:3 The sons of Reuben are also listed in Gen 46:9; Exod 6:14; Num 26:5-6.
