Jeremiah 41:8-9

8But ten men who were found among them said to Ishmael, “Do not put us to death; for we have 1stores 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 cast all the corpses of the men whom he had struck down 2because of Gedaliah, it was the 3one that King Asa had made on 4account of Baasha, king of Israel; Ishmael the son of Nethaniah filled it with the slain.
