I. A declaration of war against Edom, (v. 1): "We have heard a rumour, or rather an order, from the Lord, the God of hosts; he has given the word of command; it is his counsel and decree, which can neither be reversed nor resisted, that all who do mischief to his people shall certainly bring mischief upon themselves. We have heard a report that God is raised up out of his holy habitation, and is preparing his throne for judgment; and an ambassador is sent among the heathen," a herald rather, some minister or messenger of Providence, to alarm the nations, or the Lord's prophets, who gave each nation its burden. Those whom God employs cry to each other, Arise ye, stir up yourselves and one another, and let us rise up against Edom in battle. The confederate forces under Nebuchadnezzar thus animate themselves and one another to make a descent upon that country: Gather yourselves together, and come against her; so it is in the parallel place, Jer. xlix. 14. Note, When God has bloody work to do among the enemies of his church he will find out and fit up both hands and hearts to do it.
