Jeremiah 38:16 (KJV)

Then Zedekiah the king sent, and took Jeremiah the prophet unto him into the third entry that is in the house of the Lord: and the king said unto Jeremiah, I will ask thee a thing; hide nothing from me.

Then Jeremiah said unto Zedekiah, If I declare it unto thee, wilt thou not surely put me to death? and if I give thee counsel, wilt thou not hearken unto me?

So Zedekiah the king sware secretly unto Jeremiah, saying, As the Lord 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.

Then said Jeremiah unto Zedekiah, Thus saith the Lord, the God of hosts, the God of Israel; If thou wilt assuredly go forth unto the king of Babylon’s princes, then thy soul shall live, and this city shall not be burned with fire; and thou shalt live, and thine house:

But if thou wilt not go forth to the king of Babylon’s princes, then shall this city be given into the hand of the Chaldeans, and they shall burn it with fire, and thou shalt not escape out of their hand.
