Now then do it: for the LORD hath spoken of David, saying, By the hand of my servant David I will save my people Israel from the hand of the Philistines, and from the hand of all their enemies.

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 to the people, I will surely go forth with you myself also.
