John Calvin's Bible Commentary
Jeremiah 39:4
he then adds, After Zedekiah saw them, etc. ; not that he came to that part, but after he understood that that part of the city was occupied by the enemies; for matters then had come to an extremity. Then he fled with his men of war. And here is set before us a sad spectacle: men in no way trained up for war were left in the city, women also and children were left there, while the men of war fled, inasmuch as their condition was worse, because they had delayed the taking of the city. It was then according to what is commonly done, that they fled. We yet see that ungodly men, after having long despised heavenly truth, flee in time of danger, and are so filled with terror, that they cast themselves headlong into many perils.

Some think that there was a subterranean passage, which had a door in the middle of the garden, and had also an egress at the other end in the plain of Jericho, as we shall hereafter see. And that region was barren, and therefore solitary. Hence the king entertained confidence; but he found, at length, how certain was prophetic truth; for it is said afterwards, that the Chaldeans followed and took him. But this circumstance, as I have said, ought to be carefully observed, that the king, as the Prophet tells us, fled. through a secret way, during the darkness of the night, and escaped.
