Jeremiah 41:8-9

8But ten men were found among them that said unto Ishmael, Do not kill us, for we have hidden stores in the field, of wheat, and of barley, and of oil, and of honey. So he forbore, and did not kill them among their brethren.

9And the pit into which Ishmael had cast all the dead bodies of the men whom he had slain by the side of Gedaliah was the one which Asa the king had made for fear of Baasha king of Israel: Ishmael the son of Nethaniah filled it with the slain.
