7 When all the leaders of the forces in the open country and their troops heard that the king of Babylon had appointed Gedaliah son of Ahikam governor in the land, and had committed to him men, women, and children, those of the poorest of the land who had not been taken into exile to Babylon, 8 they went to Gedaliah at Mizpah-Ishmael son of Nethaniah, Johanan son of Kareah, Seraiah son of Tanhumeth, the sons of Ephai the Netophathite, Jezaniah son of the Maacathite, they and their troops. 9 Gedaliah son of Ahikam son of Shaphan swore to them and their troops, saying, "Do not be afraid to serve the Chaldeans. Stay in the land and serve the king of Babylon, and it shall go well with you. 10 As for me, I am staying at Mizpah to represent you before the Chaldeans who come to us; but as for you, gather wine and summer fruits and oil, and store them in your vessels, and live in the towns that you have taken over." 11 Likewise, when all the Judeans who were in Moab and among the Ammonites and in Edom and in other lands heard that the king of Babylon had left a remnant in Judah and had appointed Gedaliah son of Ahikam son of Shaphan as governor over them, 12 then all the Judeans returned from all the places to which they had been scattered and came to the land of Judah, to Gedaliah at Mizpah; and they gathered wine and summer fruits in great abundance.

Ishmael's Conspiracy against Gedaliah

13 Now Johanan son of Kareah and all the leaders of the forces in the open country came to Gedaliah at Mizpah 14 and said to him, "Are you at all aware that Baalis king of the Ammonites has sent Ishmael son of Nethaniah to take your life?" But Gedaliah son of Ahikam would not believe them. 15 Then Johanan son of Kareah spoke secretly to Gedaliah at Mizpah, "Please let me go and kill Ishmael son of Nethaniah, and no one else will know. Why should he take your life, so that all the Judeans who are gathered around you would be scattered, and the remnant of Judah would perish?" 16 But Gedaliah son of Ahikam said to Johanan son of Kareah, "Do not do such a thing, for you are telling a lie about Ishmael."

Matthew Henry's Commentary on Jeremiah 40:7-16

Commentary on Jeremiah 40:7-16

(Read Jeremiah 40:7-16)

Jeremiah had never in his prophecies spoken of any good days for the Jews, to come immediately after the captivity; yet Providence seemed to encourage such an expectation. But how soon is this hopeful prospect blighted! When God begins a judgment, he will complete it. While pride, ambition, or revenge, bears rule in the heart, men will form new projects, and be restless in mischief, which commonly ends in their own ruin. Who would have thought, that after the destruction of Jerusalem, rebellion would so soon have sprung up? There can be no thorough change but what grace makes. And if the miserable, who are kept in everlasting chains for the judgment of the great day, were again permitted to come on earth, the sin and evil of their nature would be unchanged. Lord, give us new hearts, and that new mind in which the new birth consists, since thou hast said we cannot without it see thy heavenly kingdom.
