John Gill Commentary Jeremiah 32:3

"For Zedekiah king of Judah had shut him up, saying, Wherefore dost thou prophesy, and say, Thus saith Jehovah, Behold, I will give this city into the hand of the king of Babylon, and he shall take it;" — Jeremiah 32:3 (ASV)

For Zedekiah king of Judah has shut him up
In prison, at least in the court of the prison; he had given orders for his imprisonment, which were executed, and it was the same as if he had done it himself; the reason of which was, as follows: saying, wherefore dost thou prophesy, and say, thus saith the Lord ,
behold, I will give this city into the hand of the king of Babylon, and
he shall take it ?
meaning the city of Jerusalem, now besieged by the king of Babylon. This prophecy stands in (Jeremiah 34:1–3) ; the prophecies of this book not being put together in proper order of time.
