C. F. Keil and Franz Delitzsch on 2 Kings 25:25

2Ki 25:25

In the seventh month, i.e., hardly two months after the destruction of Jerusalem, came Ishmael with ten men to Gedaliah at Mizpah, and murdered him together with the Jews and Chaldaeans, whom he had with him as soldiers to do his bidding and for his protection. This occurred, according to Jer 41:1., when Gedaliah had received them hospitably and had invited them to eat with him. Ishmael was instigated to commit this murder by the Ammonitish king Baalis, and Gedaliah had previously been made acquainted with the intended crime and put upon his guard by Johanan, but had put no faith in the information (Jer 40:13-16).
