7 When all the army officers and their men who were still in the open country heard that the king of Babylon had appointed Gedaliah son of Ahikam as governor over the land and had put him in charge of the men, women and children who were the poorest in the land and who had not been carried into exile to Babylon, 8 they came to Gedaliah at Mizpah-Ishmael son of Nethaniah, Johanan and Jonathan the sons of Kareah, Seraiah son of Tanhumeth, the sons of Ephai the Netophathite, and Jaazaniah[1] the son of the Maakathite, and their men. 9 Gedaliah son of Ahikam, the son of Shaphan, took an oath to reassure them and their men. "Do not be afraid to serve the Babylonians,[2] " he said. "Settle down in the land and serve the king of Babylon, and it will go well with you. 10 I myself will stay at Mizpah to represent you before the Babylonians who come to us, but you are to harvest the wine, summer fruit and olive oil, and put them in your storage jars, and live in the towns you have taken over." 11 When all the Jews in Moab, Ammon, Edom and all the other countries heard that the king of Babylon had left a remnant in Judah and had appointed Gedaliah son of Ahikam, the son of Shaphan, as governor over them, 12 they all came back to the land of Judah, to Gedaliah at Mizpah, from all the countries where they had been scattered. And they harvested an abundance of wine and summer fruit.

Ishmael's Conspiracy against Gedaliah

13 Johanan son of Kareah and all the army officers still in the open country came to Gedaliah at Mizpah 14 and said to him, "Don't you know that Baalis king of the Ammonites has sent Ishmael son of Nethaniah to take your life?" But Gedaliah son of Ahikam did not believe them. 15 Then Johanan son of Kareah said privately to Gedaliah in Mizpah, "Let me go and kill Ishmael son of Nethaniah, and no one will know it. Why should he take your life and cause all the Jews who are gathered around you to be scattered and the remnant of Judah to perish?" 16 But Gedaliah son of Ahikam said to Johanan son of Kareah, "Don't do such a thing! What you are saying about Ishmael is not true."

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.
