2 Samuel 2:12-13

Now Abner the son of Ner, went out from Mahanaim to Gibeon with the servants of Ish-bosheth the son of Saul. And Joab the son of Zeruiah and the servants of David went out and met them by the pool of Gibeon; and they sat down, one on the one side of the pool and the other on the other side of the pool.
