they took all their men and went to fight against Ishmael son of Nethaniah. They came upon him at the great pool that is in Gibeon.
Joab son of Zeruiah and the servants of David went out and met them at the pool of Gibeon. One group sat on one side of the pool, while the other sat on the other side of the pool.
And when all the people who were with Ishmael saw Johanan son of Kareah and all the leaders of the forces with him, they were glad.
