Jeremiah 41:3-10

³Ishmael also struck and killed all the Jews who were with him, that is with Gedaliah in Mizpah, and the Chaldeans who were found there, the men of war.

⁴Now it happened on the next day after the killing of Gedaliah, when no one knew about it, ⁵that eighty men came from Shechem, from Shiloh, and from Samaria with their beards shaved off, their clothes torn, and their bodies gashed, having grain offerings and incense in their hands to bring to the house of the Lord. ⁶Then Ishmael the son of Nethaniah left Mizpah to meet them, weeping as he went; and as he met them, he said to them, “Come to Gedaliah the son of Ahikam!” ⁷Yet it turned out that as soon as they came inside the city, Ishmael the son of Nethaniah and the men who were with him slaughtered them and threw them into the cistern. ⁸But ten men who were found among them said to Ishmael, “Do not put us to death, for we have supplies of wheat, barley, oil, and honey hidden in the field.” So he refrained and did not put them to death along with their companions.

⁹Now as for the cistern where Ishmael had thrown all the bodies of the men whom he had struck and killed because of Gedaliah, it was the one that King Asa had constructed on account of Baasha, king of Israel; Ishmael the son of Nethaniah filled it with the dead. ¹⁰Then Ishmael took captive all the remnant of the people who were in Mizpah, the king’s daughters and all the people who were left in Mizpah, whom Nebuzaradan the captain of the bodyguard had put in the custody of Gedaliah the son of Ahikam. Ishmael the son of Nethaniah took them captive and proceeded to cross over to the sons of Ammon.
