Jer Jeremiah, chapter Book of Jeremiah, chapter 40
Then Yochanan ben Kareach spoke to Gedalyahu in Mitzpah baseter (secretly) saying, Let me go, and I will slay Yishmael ben Netanyah, and no man shall know it. Why should he slay thee, that all the Yehudim which are gathered unto thee should be scattered, and the she'erit in Yehudah perish? 2Sa 16:9
