John Gill Bible Commentary

Then they took all the men,.... All the soldiers that were under their command; this they did at once, believing the report to be true, as they had reason to do; since they knew of Ishmael's designs, and had given notice and warning of them to Gedaliah, though he would not listen to them: and went to fight with Ishmael the son of Nethaniah: resolving to give him battle, and to revenge the innocent blood he had shed, and rescue the captives out of his hands he was carrying to the Ammonites: and found him by the great waters that are in Gibeon; taking this road to the country of Ammon, though it was not quite the direct road; either to avoid the forces of Johanan; or rather for the sake of the hid treasure at Shechem, or Shiloh, or Samaria, the ten men had promised him for their lives. These great waters were the same with the pool at Gibeon, where the servants of Ishbosheth and the servants of David met, and sat one on one side, and the other on the other; and where twelve young men on each side slew one another, and from thence called Helkathhazzurim, Sa2 2:12; and the Targum calls it "the pool of many waters, which were in Gibeon.'' Josephus (p) calls it a fountain in Hebron; which perhaps should be read Gibeon. (p) Antiqu. l. 10. c. 9. sect. 5.
