So they took all their troops and went to fight against Ishmael son of Nethaniah. They caught up with him near the large pool at Gibeon.
Joab son of Zeruiah and the servants of David also went out and confronted them at the pool of Gibeon. One group stationed themselves on one side of the pool, and the other group on the other side of the pool.
When all the people that Ishmael had taken captive saw Johanan son of Kareah and all the army officers with him, they were glad.
