40:15 Then Johanan son of Kareah spoke privately to Gedaliah there at Mizpah, “Let me go and kill Ishmael the son of Nethaniah before anyone knows about it. Otherwise he will kill you and all the Judeans who have rallied around you will be scattered. Then what remains of Judah will disappear.” 40:16 But Gedaliah son of Ahikam said to Johanan son of Kareah, “Do not do that because what you are saying about Ishmael is not true.”
