1 Chronicles 5:18 (KJV)

And they dwelt in Gilead in Bashan, and in her towns, and in all the suburbs of Sharon, upon their borders.

All these were reckoned by genealogies in the days of Jotham king of Judah, and in the days of Jeroboam king of Israel.

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.

And they made war with the Hagarites, with Jetur, and Nephish, and Nodab.

And they were helped against them, and the Hagarites were delivered into their hand, and all that were with them: for they cried to God in the battle, and he was intreated of them; because they put their trust in him.
