Jeremiah 40:7-16

7 Now when all the captains of the forces who were in the fields, even they and their men, heard that the king of Babylon had made Gedaliah the son of Ahikam governor in the land, and had committed to him men, and women, and children, and of the poorest of the land, of those who were not carried away captive to Babylon;
8 then they came to Gedaliah to Mizpah, [to wit], Ishmael the son of Nethaniah, and Johanan and Jonathan the sons of Kareah, and Seraiah the son of Tanhumeth, and the sons of Ephai the Netophathite, and Jezaniah the son of the Maacathite, they and their men.
9 Gedaliah the son of Ahikam the son of Shaphan swore to them and to their men, saying, Don't be afraid to serve the Chaldeans: dwell in the land, and serve the king of Babylon, and it shall be well with you.
10 As for me, behold, I will dwell at Mizpah, to stand before the Chaldeans who shall come to us: but you, gather you wine and summer fruits and oil, and put them in your vessels, and dwell in your cities that you have taken.
11 Likewise when all the Jews who were in Moab, and among the children of Ammon, and in Edom, and who were in all the countries, heard that the king of Babylon had left a remnant of Judah, and that he had set over them Gedaliah the son of Ahikam, the son of Shaphan;
12 then all the Jews returned out of all places where they were driven, and came to the land of Judah, to Gedaliah, to Mizpah, and gathered wine and summer fruits very much.
13 Moreover Johanan the son of Kareah, and all the captains of the forces who were in the fields, came to Gedaliah to Mizpah,
14 and said to him, Do you know that Baalis the king of the children of Ammon has sent Ishmael the son of Nethaniah to take your life? But Gedaliah the son of Ahikam didn't believe them.
15 Then Johanan the son of Kareah spoke to Gedaliah in Mizpah secretly, saying, Please let me go, and I will kill Ishmael the son of Nethaniah, and no man shall know it: why should he take your life, that all the Jews who are gathered to you should be scattered, and the remnant of Judah perish?
16 But Gedaliah the son of Ahikam said to Johanan the son of Kareah, You shall not do this thing; for you speak falsely of Ishmael.
