Jeremiah 40:13-16

13Then Johanan son of Kareah and all the commanders of the forces that were in the field came to Gedaliah to Mizpah

14and said to him, “Are you aware that Baalis the king of Ammon’s children has sent Ishmael son of Nethaniah to take your life?” But Gedaliah son of Ahikam did not believe them.

15Then Johanan son of Kareah spoke privately to Gedaliah at Mizpah, saying, “Let me go now, and I will slay Ishmael son of Nethaniah, and no one will know it. Why should he take your life, so that all the Jews that are gathered to you would be scattered, and the remnant of Judah perish?’

16But Gedaliah son of Ahikam said to Johanan son of Kareah, “Don’t do this thing! For what you are saying about Ishmael is a lie.”
