Jeremiah 41:17 (KJV)

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:

And they departed, and dwelt in the habitation of Chimham, which is by Beth–lehem, to go to enter into Egypt,

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.
