Next Ishmael, the son of Nethaniah and grandson of Elishama, who was a royal family member, came to Mizpah in the seventh month that may have been the feast of Tents. Ishmael was an officer of the king also. He came with 10 men to greet Governor Gedaliah. They even ate a meal together at Mizpah. Thus this seems like everything was okay. Ishmael was mad either because he was passed over by not being named governor or he was mad at the Babylonians for taking his king, King Zedekiah.
Johanan, the son of Kareah, was one of the open field leaders against Babylon. He and the other rebel leaders came to Mizpah to see what was going on there. When he got there, he told Governor Gedaliah that the king of the Ammonites, King Baalis, had sent Ishmael, the son of Nethaniah, also another Judean country leader, to kill Gedaliah. They have actually found a seal from this King Baalis of Ammon dated around 600 BCE. However, Gedaliah did not believe him, since Ishmael was also a member of the Judean royal household.
