Jeremiah 40:13-16

13Kareah’s son Johanan and all the army commanders who were still in the country came to Gedaliah at Mizpah.

14They asked him, “Do you know that King Baalis of the Ammonites has sent Ishmael, Nethaniah’s son, to kill you?” However, Gedaliah, son of Ahikam, didn’t believe them.

15Then Johanan, Kareah’s son, secretly asked Gedaliah at Mizpah, “Let me kill Ishmael, Nethaniah’s son. No one will know about it. Why should he kill you? All the Jews who have gathered around you would scatter. What is left of Judah would disappear.”

16Gedaliah, son of Ahikam, told Johanan, Kareah’s son, “Don’t do that! What you are saying about Ishmael is a lie.”
