And king Zedekiah swore secretly unto Jeremiah, saying, As Jehovah liveth, that made us this soul, I will not put thee to death, neither will I give thee into the hand of these men that seek thy life.

And Johanan the son of Kareah spoke to Gedaliah in Mizpah secretly, saying, Let me go, I pray thee, and I will smite Ishmael the son of Nethaniah and no man shall know it: why should he take thy life, and all they of Judah who are gathered unto thee be scattered, and the remnant of Judah perish?
