These are the people who waged war in the time of Saul (King)..
1 Chr 5:10In the days of King Saul they made war on the Hagrites, who fell by their hand, and they lived in their tents throughout all the region east of Gilead.
1 Chr 5:18The Reubenites, the Gadites, and the half-tribe of Manasseh had valiant men, who carried shield and sword, and drew the bow, expert in war, forty-four thousand seven hundred and sixty, able to go to war.1 Chr 5:19They made war on the Hagrites, Jetur, Naphish, and Nodab.1 Chr 5:20And when they cried to God in battle, he granted their plea, because they trusted in him. So the Hagrites and all who were with them were given into their hand.1 Chr 5:21They carried off their livestock: fifty thousand of their camels, two hundred fifty thousand sheep, two thousand donkeys, and a hundred thousand people.1 Chr 5:22For many fell slain, because the war was of God. And they lived in their place until the exile.
