1 Chronicles 12:13 (KJV)

And of the Gadites there separated themselves unto David into the hold to the wilderness men of might, and men of war fit for the battle, that could handle shield and buckler, whose faces were like the faces of lions, and were as swift as the roes upon the mountains;

Ezer the first, Obadiah the second, Eliab the third,

Mishmannah the fourth, Jeremiah the fifth,

Attai the sixth, Eliel the seventh,

Johanan the eighth, Elzabad the ninth,

These were of the sons of Gad, captains of the host: one of the least was over an hundred, and the greatest over a thousand.

These are they that went over Jordan in the first month, when it had overflown all his banks; and they put to flight all them of the valleys, both toward the east, and toward the west.

And there came of the children of Benjamin and Judah to the hold unto David.

And David went out to meet them, and answered and said unto them, If ye be come peaceably unto me to help me, mine heart shall be knit unto you: but if ye be come to betray me to mine enemies, seeing there is no wrong in mine hands, the God of our fathers look thereon, and rebuke it.

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.
