John Gill Commentary Jeremiah 34:2

"Thus saith Jehovah, the God of Israel, Go, and speak to Zedekiah king of Judah, and tell him, Thus saith Jehovah, Behold, I will give this city into the hand of the king of Babylon, and he shall burn it with fire:" — Jeremiah 34:2 (ASV)

Thus says the Lord, the God of Israel Who, though the covenant God of Israel, yet provoked by their sins, sends the following message to their king: go and speak to Zedekiah king of Judah, and tell him : alone; and tell it to no other but him, at least at present; the message being more peculiar to him, and must, had it been told to the people, been very disheartening to them:

behold, I will give this city into the hand of the king of Babylon , and he shall burn it with fire ; see (Jeremiah 32:3) ; which was exactly accomplished, (Jeremiah 52:13) .
