Jeremiah 41:6-9

6Then Ishmael the son of Nethaniah left Mizpah to meet them, 1weeping 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 2slaughtered 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 3supplies 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 4because of Gedaliah, it was the 5one that King Asa had constructed on 6account of Baasha, king of Israel; Ishmael the son of Nethaniah filled it with the dead.
