'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, his helpers in war.

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