Behold now, this city is near to flee unto, and it is a little one: Oh, let me escape there, (is it not a little one?) and my soul shall live.

Incline your ear, and come unto me: hear, and your soul shall live; and I will make an everlasting covenant with you, even the sure mercies of David.

Then said Jeremiah unto Zedekiah, Thus says the LORD, the God of hosts, the God of Israel; If you will assuredly go forth unto the king of Babylon's princes, then your soul shall live, and this city shall not be burned with fire; and you shall live, and your house:

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