Jeremiah 40:11-15

11Likewise, when all the Judeans who were in Moab and among the Ammonites and in Edom and in other lands heard that the king of Babylon had left a remnant in Judah and had appointed Gedaliah the son of Ahikam, son of Shaphan, as governor over them,

12then all the Judeans returned from all the places to which they had been driven and came to the land of Judah, to Gedaliah at Mizpah. And they gathered wine and summer fruits in great abundance.

13Now Johanan the son of Kareah and all the leaders of the forces in the open country came to Gedaliah at Mizpah

14and said to him, "Do you know that Baalis the king of the Ammonites has sent Ishmael the son of Nethaniah to take your life?" But Gedaliah the son of Ahikam would not believe them.

15Then Johanan the son of Kareah spoke secretly to Gedaliah at Mizpah, "Please let me go and strike down Ishmael the son of Nethaniah, and no one will know it. Why should he take your life, so that all the Judeans who are gathered about you would be scattered, and the remnant of Judah would perish?"
