1 Chronicles 12:8-18
12:8 Some of the Gadites joined David at the stronghold in the desert. They were warriors who were trained for battle; they carried shields and spears. They were as fierce as lions and could run as quickly as gazelles across the hills.
12:9 Ezer was the leader, Obadiah the second in command, Eliab the third,
12:10 Mishmannah the fourth, Jeremiah the fifth,
12:11 Attai the sixth, Eliel the seventh,
12:12 Johanan the eighth, Elzabad the ninth,
12:13 Jeremiah the tenth, and Machbannai the eleventh.
12:14 These Gadites were military leaders; the least led a hundred men, the greatest a thousand.
12:15 They crossed the Jordan River in the first month, when it was overflowing its banks, and routed those living in all the valleys to the east and west.
12:16 Some from Benjamin and Judah also came to David’s stronghold.
12:17 David went out to meet them and said, “If you come to me in peace and want to help me, then I will make an alliance with you. But if you come to betray me to my enemies when I have not harmed you, may the God of our ancestors take notice and judge!”
12:18 But a spirit empowered Amasai, the leader of the thirty warriors, and he said:
“We are yours, O David!
We support you, O son of Jesse!
May you greatly prosper!
May those who help you prosper!
Indeed your God helps you!”
So David accepted them and made them leaders of raiding bands.
