Chapter 21: Babylon is fallen!
The burden against the Wilderness of the Sea (ie Babylon). An army from Elam (Persia) marches against it. A report will come to the watchman: Babylon is fallen, is fallen! The (brief) burden against Dumah (Edom): the watchman will report that the morning comes, and also the night. The burden against Arabia: within a year, all the glory of Kedar will fall.
Chapter 22: A Nail in a Sure Place
The burden against the Valley of Vision (Jerusalem). An army is coming, against which there is no deliverance. Instead of turning their hearts in humble repentance to the Lord, the inhabitants of Jerusalem said, ‘Let us eat and drink, for tomorrow we die!’ Shebna, Hezekiah’s chief steward, is denounced. Shebna will be replaced by Eliakim. He will be given the key of the house of David.
