Jeremiah 40:6, 9, 14

Then went Jeremiah unto Gedaliah the son of Ahikam to Mizpah; and dwelt with him among the people that were left in the land.

And Gedaliah the son of Ahikam the son of Shaphan sware unto them and to their men, saying, Fear not to serve the Chaldeans: dwell in the land, and serve the king of Babylon, and it shall be well with you.

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.
