Jeremiah 40:13-16

Meanwhile, Johanan son of Kareah and all the commanders of the armies in the countryside came to Gedaliah at Mizpah and warned him, “Don’t you realize that Baalis, king of the Ammonites, has sent Ishmael son of Nethaniah  to kill you? ” But Gedaliah son of Ahikam would not believe them. Then Johanan son of Kareah suggested to Gedaliah in private at Mizpah, “Let me go kill Ishmael son of Nethaniah. No one will know it. Why should he kill you and allow all of Judah that has gathered around you to scatter and the remnant of Judah to perish? ”  But Gedaliah son of Ahikam responded to Johanan son of Kareah, “Don’t do that! What you’re saying about Ishmael is a lie.”
