Jeremiah 40:13-15

Moreover Johanan the son of Kareah, and all the captains of the forces that {were} in the fields, came to Gedaliah to Mizpah, And said unto him, Dost thou certainly know that Baalis the king of the Ammonites hath sent Ishmael the son of Nethaniah to slay thee? But Gedaliah the son of Ahikam believed them not. {to slay...: Heb. to strike thee in soul?} 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 slay thee, that all the Jews which are gathered unto thee should be scattered, and the remnant in Judah perish?
