Jeremiah 40:6, 9, 14

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

And Gedaliah the son of Ahikam, the son of Shaphan, took an oath before them and their men, saying, “Do not be afraid to serve the Chaldeans. Dwell in the land and serve the king of Babylon, and it shall be well with you.

and said to him, “Do you certainly know that Baalis the king of the Ammonites has sent Ishmael the son of Nethaniah to murder you?” But Gedaliah the son of Ahikam did not believe them.
