Amasai Scripture - 1 Chronicles 12:18

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.
