THE WARNING FOLLOWED BY A PROMISE. It is ever God's care to prevent men from being "swallowed up with overmuch sorrow" (2 Corinthians 2:7). As long as he is not about to "make a full end" (Jeremiah 4:27), he mingles promises with his threats, words of cheer with words of warning.
So now the prophet is directed to attach to his four verses of denunciation (Isaiah 29:1-4) four others of encouragement, and to declare the utter discomfiture of the vast host of enemies which for a time has besieged and "distressed" Ariel.
