Matthew Poole and continuators on Jeremiah 38:17

17 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 Babylons princes, then thy soul shall live , and this city shall not be burnt with fire, and thou shalt live, and thine house .

That is, thou shalt live.

And thou shalt save the City from being burned with fire, and thy Wives and Children from death. God did certainly know that Zedekiah would not do this, though it was in his power to do it, yet he doth not judge it vain for him to exhort him to do it, and to annex such a promise; for thereby he was left inexcusable, in his not saving the City, and his Relations lives.
