John Gill Bible Commentary

Moreover he put out Zedekiah's eyes,.... By what means is not certain; however, hereby the prophecy of Jeremiah was fulfilled, that his eyes should see the king of Babylon, as they did, before they were put out, and that he should not die by the sword, Jer 34:3; and also the prophecy of Ezekiel, Eze 12:13; that he should be brought to Babylon, and yet should not see it; for his eyes were put out before he was carried there: a full proof this of the prescience of God; of his foreknowledge of future and contingent events; of the truth and certainty of prophecy, and of the authority of divine revelation: and bound him with chains, to carry him to Babylon; with two brass or iron chains, or fetters, for both his legs; and thus bound he was carried to Babylon, where he remained to the day of his death.
