Jeremiah 40
15 Ref Then Johanan the son of Kareah spake to Gedaliah in Mizpah secretly, saying, Let me go, I pray thee, and I will slay Ishmael the son of Nethaniah, and no man shall know it: wherefore should he take thy life, that all the Jews that are gathered unto thee should be scattered, and the remnant of Judah perish?
16 Ref But Gedaliah the son of Ahikam said unto Johanan the son of Kareah, Thou shalt not do this thing; for thou speakest falsely of Ishmael.
