16There came of the children of Benjamin and Judah to the stronghold to David. 17David went out to meet them, and answered them, If you be come peaceably to me to help me, my heart shall be knit to you; but if [you be come] to betray me to my adversaries, seeing there is no wrong in my hands, the God of our fathers look thereon, and rebuke it. 18Then the Spirit came on Amasai, who was chief of the thirty, [and he said], Your are we, 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.
