Jeremiah 41:11

“But when Johanan the son of Kareah, etc.] The same that is mentioned (<244008>Jeremiah 40:8,13,15); and who had informed Gedaliah of Ishmael’s designs against him, but he would not believe him: and all the captains of the forces that [were] with him; his brother Jonathan, Seraiah, the sons of Ephai, and Jezaniah, (<244008>Jeremiah 40:8); heard of all the evil that Ishmael the son of Nethaniah had done; in murdering Gedaliah, and those that were with him, destroying seventy other persons he had decoyed, and carrying captive the rest of the people at Mizpah; for though Ishmael kept all this a secret as much as he could, for fear of these forces, and that he might get off clear to Ammon; yet,…”

“Johanan--the friend of Gedaliah who had warned him of Ishmael's treachery, but in vain (Jer 40:8, Jer 40:13).”

“41:11-12 Johanan and his companions learned of Gedaliah’s death in time to attack Ishmael’s party at the pool near Gibeon, which was only a few miles south of Mizpah.”

“Johanan: Jer 41:2, Jer 41:3, Jer 41:7, Jer 40:7, Jer 40:8, Jer 40:13-16, Jer 42:1, Jer 42:3, Jer 43:2-5 Jeremiah 41:12”

“\- Jer 41:11. When Johanan and the rest of the captains heard of what had taken place in Mizpah, they marched out with all their men to fight Ishmael, and came on him at the great water at Gibeon, i.e., by the pool at Gibeon which is mentioned Sa2 2:13, one of the large receptacles for water which are still found there; see on Sa2 2:13. Gibeon, now called el Jib (see on Jos 9:3), was situated only about two miles north from Mizpah; from which we may conclude that it was soon known what had happened, and the captains quickly assembled their men and marched after Ishmael.
