2 Samuel 20:6,7

Then David said to Abishai Not to Joab; lest by this means he should recover his place, and Amasa be discontented, and David's fidelity in making good his promise to Amasa be questioned. Now shall Sheba do us more harm than Absalom If he have time to gather an army; the people being highly incensed by the provocation which the men of Judah had given them. Take thy lord's servants The guards that attended David, and the standing forces which were always kept in readiness. There went out after him Joab's men A body of men whom he particularly commanded, with whom Joab also might go in some character, watching an opportunity to do what he designed.
