'Helpers' in the Bible

Now these are the men who came to David at Ziklag, while he was still shut up, because of Saul, the son of Kish; they were among the strong men, his helpers in war.

Then the spirit came on Amasai, who was chief of the captains, and he said, We are yours, David, we are on your side, O son of Jesse: may peace be with you and peace be with your helpers; for God is your helper. Then David took them into his army and made them captains of the band.
