1 Chronicles 12:19-22

19Then a spirit came upon Amasai, leader of the 30, “We are yours, David, on your side, son of Jesse. Shalom, shalom to you, and shalom to him who helps you, for your God supports you!” So David welcomed them and made them leaders of the troops.

20Some from Manasseh went over to David when he went with the Philistines to battle against Saul. But they did not help them because the Philistine rulers after consultation sent him away, saying: “It would cost us our heads if he defected to his master Saul.”

21When he went to Ziklag, these from Manasseh joined him—Adnah, Jozabad, Jediael, Michael, Jozabad, Elihu, Zillethai, the leaders of thousands that were from Manasseh.

22They helped David against the raiding bands, for all of them were valiant warriors and they were officers in the army.
