Thematic Bible: Warns gedaliah against ishmael

Meanwhile, Johanan son of Kareah and all the commanders of the armies in the field 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 strike you down?" 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 strike you down and scatter all of Judah that has gathered to you so that the remnant of Judah would perish?" read more.
But Gedaliah son of Ahikam responded to Johanan son of Kareah, "Don't do that! What you're saying about Ishmael is a lie."
