10 Ishbaal, son of Saul, was forty years old when he became king over Israel, and he reigned two years; but the house of Judah followed David.
11 In all, David was king in Hebron over the house of Judah seven years and six months.
12 Now Abner, son of Ner, and the servants of Ishbaal, Saul’s son, set out from Mahanaim for Gibeon.
13 Joab, son of Zeruiah, and the servants of David also set out and encountered them at the pool of Gibeon. And they sat down, one group on one side of the pool and the other on the opposite side.
14 Then Abner said to Joab, “Let the young men rise and perform for us.” Joab replied, “All right.”
15 So they rose and were counted off: twelve of the Benjaminites of Ishbaal, son of Saul, and twelve of David’s servants.
16 Then each one grasped his opponent’s head and thrust his sword into his opponent’s side, and they all fell down together. And so that place was named the Field of the Sides; it is in Gibeon.
