Jeremiah 41:9

Now, the pit wherein Ishmael had cast all the dead bodies of the men whom he had slain because of Gedaliah, literally, "at the hand of Gedaliah," that is, next to Gedaliah, whom he had first cast into this trench or cistern, was it which Asa, the king, had made for fear of Baasha, king of Israel, Cf 1 Kings 15:16; and Ishmael, the son of Netha-niah, filled it with them that were slain, a gruesome heap of his victims.
