Matthew Poole and continuators on Nahum 1:9

9 What do ye imagine against the LORD ? he will make an utter end : affliction shall not rise up the second time .

Having declared the dreadfulness of God's Power and Anger against the wicked; his goodness towards his people, and denounced future destruction against the Ninevites, and Assyrians: He doth now expostulate with them, would know what 'tis they think of God, what 'tis they design against him, and on what ground they flatter themselves into such an attempt?

The God of Israel, for however you O Ninevites, and Assyrians! will look only upon a poor, afflicted people, (weakned by many Wars,) and design to swallow them up, yet they are the people of the Lord, and you design against him what you design against them.

He will make your utter desolation to be the issue of your projects, and the punishment of your sins, vid. ver. 8. let. p.

When that storm which shall overthrow you is past, no other shall arise, because you shall be no more; as if the Prophet had said, God will at once, and for ever destroy your Empire and City.
