The former verse assures us of what it foretold, and the assurance is the word and truth of God; this verse tells us when this shall be. Shall be destitute: this phrase is Ezekiel 12:19. That whereof it was full; men and women, cattle, food, wealth, and peace. When I shall smite by the sword, the destroying sword of the Chaldeans. Then shall they know that I am the Lord; then shall they confess it to the glory of God's power and justice.
