1 Chronicles 12:8-18

8And of the Gadites there separated themselves unto David to the stronghold in the wilderness, mighty men of valor, men trained for war, that could handle shield and spear; whose faces were like the faces of lions, and they were as swift as the roes upon the mountains: 9Ezer the chief, Obadiah the second, Eliab the third, 10Mishmannah the fourth, Jeremiah the fifth, 11Attai the sixth, Eliel the seventh, 12Johanan the eighth, Elzabad the ninth, 13Jeremiah the tenth, Machbannai the eleventh. 14These of the sons of Gad were captains of the host: he that was least was equal to a hundred, and the greatest to a thousand. 15These are they that went over the Jordan in the first month, when it had overflowed all its banks; and they put to flight all them of the valleys, both toward the east and toward the west.

16And there came of the children of Benjamin and Judah to the stronghold unto David. 17And David went out to meet them, and answered and said unto them, If ye be come peaceably unto me to help me, my heart shall be knit unto you; but if ye be come to betray me to mine adversaries, seeing there is no wrong in my hands, the God of our fathers look thereon, and rebuke it. 18Then 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.
