Jeremiah 40:13-16

13Kareah's son Johanan came to Mizpah to see Gedaliah. He came with the other army officers who had been hiding in the country.

14They said to Gedaliah, ‘You should know that King Baalis of Ammon has sent Nethaniah's son Ishmael to kill you.’ But Gedaliah did not believe them.

15So while Johanan was in Mizpah, he went to speak to Gedaliah alone. He said, ‘Let me go and kill Nethaniah's son Ishmael. Nobody will know who did it. If I do not kill him, he will surely kill you. Then the people of Judah who are here with you will run away. The few people who still remain in Judah will all disappear.’

16But Ahikam's son Gedaliah, said to Kareah's son Johanan, ‘Do not do that! I do not believe the things that you tell me about Ishmael.’
