These words seem to have been addressed to the Chaldeans rather than to the Medes or the Persians, as some expound them; for this is favored by the context; for as he bids them first to raise a standard on the walls, so he adds, Increase the watch, which refers to the citizens of Babylon, and then he says, set the watchmen. All this cannot apply to the Persians and the Medes, but must be referred to the besieged, as being most suitable to them. I do not then doubt but that the Prophet here treats, with a taunt, all the efforts the Chaldeans would make for the defense of their city. For not only they who attack a city raise a standard, but also they who are besieged, and this as a sign of confidence, in order to show that they possess sufficient courage to check their enemies, and to sustain all their attacks.

The Prophet, in short, means, that he brought forth nothing but what God had decreed. For words are often heedlessly uttered, and the reality and the words are not always connected; but Jeremiah testifies that he had taken what he announced from the hidden and immutable counsel of God. Then he adds, what he hath spoken or said; and this refers to his doctrine or his prediction. It follows, --
