2 Samuel 18:32

And David numbered the people that were with him, and set captains of thousands and captains of hundreds over them.

And David sent forth a third part of the people under the hand of Joab, and a third part under the hand of Abishai the son of Zeruiah, Joab's brother, and a third part under the hand of Ittai the Gittite. And the king said unto the people, I will surely go forth with you myself also.

But the people answered, Thou shalt not go forth: for if we flee away, they will not care for us; neither if half of us die, will they care for us: but now thou art worth ten thousand of us: therefore now it is better that thou succour us out of the city.

And the king said unto them, What seemeth you best I will do. And the king stood by the gate side, and all the people came out by hundreds and by thousands.
