1 Chronicles 5:3-18

3 The sons, I say, of Reuben the firstborn of Israel were, Hanoch, and Pallu, Hezron, and Carmi.
4 The sons of Joel; Shemaiah his son, Gog his son, Shimei his son,
5 Micah his son, Reaia his son, Baal his son,
6 Beerah his son, whom Tilgathpilneser king of Assyria carried away captive: he was prince of the Reubenites.
7 And his brethren by their families, when the genealogy of their generations was reckoned, were the chief, Jeiel, and Zechariah,
8 And Bela the son of Azaz, the son of Shema, the son of Joel, who dwelt in Aroer, even unto Nebo and Baalmeon:
9 And eastward he inhabited unto the entering in of the wilderness from the river Euphrates: because their cattle were multiplied in the land of Gilead.
10 And in the days of Saul they made war with the Hagarites, who fell by their hand: and they dwelt in their tents throughout all the east land of Gilead.
11 And the children of Gad dwelt over against them, in the land of Bashan unto Salcah:
12 Joel the chief, and Shapham the next, and Jaanai, and Shaphat in Bashan.
13 And their brethren of the house of their fathers were, Michael, and Meshullam, and Sheba, and Jorai, and Jachan, and Zia, and Heber, seven.
14 These are the children of Abihail the son of Huri, the son of Jaroah, the son of Gilead, the son of Michael, the son of Jeshishai, the son of Jahdo, the son of Buz;
15 Ahi the son of Abdiel, the son of Guni, chief of the house of their fathers.
16 And they dwelt in Gilead in Bashan, and in her towns, and in all the suburbs of Sharon, upon their borders.
17 All these were reckoned by genealogies in the days of Jotham king of Judah, and in the days of Jeroboam king of Israel.
18 The sons of Reuben, and the Gadites, and half the tribe of Manasseh, of valiant men, men able to bear buckler and sword, and to shoot with bow, and skilful in war, were four and forty thousand seven hundred and threescore, that went out to the war.
