'Helpers' in the Bible

Now these are those who came to David to Ziklag, while he yet kept himself close because of Saul the son of Kish; and they were among the mighty men, his helpers in war.

Then the Spirit came on Amasai, who was chief of the thirty, [and he said], "We are yours, David, and on your side, you son of Jesse: peace, peace be to you, and peace be to your helpers; for your God helps you." Then David received them, and made them captains of the band.
