8 Men from the tribe of Gad also joined David at his fortress in the desert and served as his warriors. They were also brave soldiers—fierce as lions and quick as gazelles. They were always prepared to fight with shields and spears.
9-13 There were eleven of them, ranked in the following order: Ezer the leader, then Obadiah, Eliab, Mishmannah, Jeremiah, Attai, Eliel, Johanan, Elzabad, Jeremiah, and Machbannai.
14 All these men were army officers; some were high-ranking officers over a thousand troops, and others were officers over a hundred troops.
15 Earlier, they had crossed the River Jordan when it flooded, and they chased out the people who lived in the valleys on each side of the river.
16 One time a group of men from the tribes of Benjamin and Judah went to the fortress where David was staying.
17 David met them outside and said, “If you are coming as friends to fight on my side, then stay and join us. But if you try to turn me over to my enemies, the God our ancestors worshipped will punish you, because I have done nothing wrong.”
18 Amasai, who later became the leader of the Thirty Warriors, was one of these men who went to David. God's Spirit took control of him, and he said, “We will join you, David son of Jesse! You and your followers will always be successful, because God fights on your side.”So David agreed to let them stay, and he even put them in charge of his soldiers who raided enemy villages.
