'Soul Shall Live' in the Bible

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