Jeremiah 40:15-16

Then Johanan son of Kareah spoke to Gedaliah in private at Mizpah. He said, “Let me go and kill Ishmael son of Nethaniah. No one will know anything about it. We should not let Ishmael kill you. Then all the Jews gathered around you would be scattered to different countries again, and the few people of Judah who are left alive would be lost.” But Gedaliah son of Ahikam said to Johanan son of Kareah, “Do not kill Ishmael! The things you are saying about Ishmael are not true.”
