Jeremiah 39:12

It is indeed probable that the king of Babylon had heard of Jeremiah; and though he was in prison, yet the Word of God, which he boldly proclaimed, was not bound. Then the report of this might have reached the king of Babylon: and hence it was, that he was disposed to preserve him; for he had given a faithful counsel to Zedekiah. But Nebuchadnezzar no doubt regarded only his own advantage; and hence we ought to bear in mind the wonderful goodness of God in preserving, as it were, by his own hand, the life of the Prophet; so that in extremities no one touched him, but he remained free and quiet, as we shall hereafter see. But we must put off the rest until to-morrow.
