Jeremiah 40:13-14

Moreover Johanan the son of Kareah, and all the captains of the forces that were in the fields, came to Gedaliah to Mizpah,

And said unto him, Dost thou certainly know that Baalis the king of the Ammonites hath sent Ishmael the son of Nethaniah to slay thee? But Gedaliah the son of Ahikam believed them not.
