'Helpers' in the Bible

Now these are they that 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, helpers of the war.

Then the spirit came upon Amasai, who was chief of the captains, and he said, Thine are we, David, and on thy side, thou son of Jesse: peace, peace be unto thee, and peace be to thine helpers; for thy God helpeth thee. Then David received them, and made them captains of the band.
