Jeremiah 41:9 NIrV

[9] But he had thrown into the empty well all the bodies of the men he had killed. That included Gedaliah’s body. The well was the one King Asa had made. He had made it when he strengthened Mizpah against attack by Baasha, the king of Israel. Ishmael, the son of Nethaniah, filled it with the bodies of those he had killed.
