And Joab the son of Zeruiah and the servants of David went out and met together by the pool of Gibeon; and they sat down, the one on one side of the pool and the other on the other side of the pool.

So Joab and Abishai his brother slew Abner, because he had slain their brother Asahel at Gibeon in the battle.

Then said the king to Amasa, "Assemble me the men of Judah within three days, and be thou present here."

So Amasa went to assemble the men of Judah, but he tarried longer than the set time which he had appointed him.
