VIII. The enemy that God will send against them shall be inexorable, probably being by some provocation or other more than ordinarily exasperated against them; or, in whatever way it may be brought about, God himself will stir up the Medes to use this severity with the Babylonians. He will not only serve his own purposes by their dispositions and designs, but will put it into their hearts to make this attempt upon Babylon, and suffer them to prosecute it with all this fury. God is not the author of sin, but he would not permit it if he did not know how to bring glory to himself out of it. These Medes, in conjunction with the Persians, shall make thorough work of it; for, 1. They shall take no bribes, v. 17. All that men have they would give for their lives, but the Medes shall not regard silver; it is blood they thirst for, not gold; no man's riches shall with them be the ransom of his life. 2. They shall show no pity (v. 18), not to the young men that are in the prime of their time—they shall shoot them through with their bows, and then dash them to pieces; not to the age of innocency—they shall have no pity on the fruit of the womb, nor spare little children, whose cries and frights one would think should make even marble eyes to weep, and hearts of adamant to relent. Pause a little here and wonder, (1.) That men should be thus cruel and inhuman, and so utterly divested of all compassion; and in it see how corrupt and degenerate the nature of man has become. (2.) That the God of infinite mercy should suffer it, nay, and should make it to be the execution of his justice, which shows that, though he is gracious, yet he is the God to whom vengeance belongs. (3.) That little infants, who have never been guilty of any actual sin, should be thus abused, which shows that there is an original guilt by which life is forfeited as soon as it is had.
