27:1-11 Jeremiah is to prepare a sign that all the neighbouring countries would be made subject to the king of Babylon. God asserts his right to dispose of kingdoms as he pleases. Whatever any have of the good things of this world, it is what God sees fit to give; we should therefore be content. The things of this world are not the best things, for the Lord often gives the largest share to bad men. Dominion is not founded in grace. Those who will not serve the God who made them, shall justly be made to serve their enemies that seek to ruin them. Jeremiah urges them to prevent their destruction, by submission. A meek spirit, by quiet submission to the hardest turns of providence, makes the best of what is bad. Many persons may escape destroying providences, by submitting to humbling providences. It is better to take up a light cross in our way, than to pull a heavier on our own heads. The poor in spirit, the meek and humble, enjoy comfort, and avoid many miseries to which the high-spirited are exposed. It must, in all cases, be our interest to obey God's will.

But Neriglissar and Labosodarchod were not in the direct male line; so that the prophecy held good to "his son and his son's son," and the intermediate two are omitted.
