Jeremiah 41:17 (KJV)

Then they took all the men, and went to fight with Ishmael the son of Nethaniah, and found him by the great waters that are in Gibeon.

Now it came to pass, that when all the people which were with Ishmael saw Johanan the son of Kareah, and all the captains of the forces that were with him, then they were glad.

So all the people that Ishmael had carried away captive from Mizpah cast about and returned, and went unto Johanan the son of Kareah.

But Ishmael the son of Nethaniah escaped from Johanan with eight men, and went to the Ammonites.

Then took Johanan the son of Kareah, and all the captains of the forces that were with him, all the remnant of the people whom he had recovered from Ishmael the son of Nethaniah, from Mizpah, after that he had slain Gedaliah the son of Ahikam, even mighty men of war, and the women, and the children, and the eunuchs, whom he had brought again from Gibeon:

Because of the Chaldeans: for they were afraid of them, because Ishmael the son of Nethaniah had slain Gedaliah the son of Ahikam, whom the king of Babylon made governor in the land.
