'Soul Shall Live' in the Bible

Then said Jeremiah unto Zedekiah, Thus saith Jehovah, the God of hosts, the God of Israel: If thou wilt 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 thy house.

But Jeremiah said, They shall not deliver thee. Obey, I beseech thee, the voice of Jehovah, in that which I speak unto thee: so it shall be well with thee, and thy soul shall live.
