1 Chronicles 5:1-13

The oldest son of Israel was Reuben. But since he dishonored his father by sleeping with one of his father’s concubines, his birthright was given to the sons of his brother Joseph. For this reason, Reuben is not listed in the genealogical records as the firstborn son. The descendants of Judah became the most powerful tribe and provided a ruler for the nation, but the birthright belonged to Joseph. The sons of Reuben, the oldest son of Israel, were Hanoch, Pallu, Hezron, and Carmi. The descendants of Joel were Shemaiah, Gog, Shimei, Micah, Reaiah, Baal, and Beerah. Beerah was the leader of the Reubenites when they were taken into captivity by King Tiglath-pileser of Assyria. Beerah’s relatives are listed in their genealogical records by their clans: Jeiel (the leader), Zechariah, and Bela son of Azaz, son of Shema, son of Joel. The Reubenites lived in the area that stretches from Aroer to Nebo and Baal-meon. And since they had so many livestock in the land of Gilead, they spread east toward the edge of the desert that stretches to the Euphrates River. During the reign of Saul, the Reubenites defeated the Hagrites in battle. Then they moved into the Hagrite settlements all along the eastern edge of Gilead. Next to the Reubenites, the descendants of Gad lived in the land of Bashan as far east as Salecah. Joel was the leader in the land of Bashan, and Shapham was second-in-command, followed by Janai and Shaphat. Their relatives, the leaders of seven other clans, were Michael, Meshullam, Sheba, Jorai, Jacan, Zia, and Eber.
