This chapter is a continuation of the prophecy against Moab; in which the prophet gives good advice, but in case of a haughty neglect of it, which he foresaw, threatens with ruin, and fixes a time for it. He advises the Moabites to pay their tribute to the king of Judah, or otherwise they should be turned out of their land, as a bird out of its nest, Isa 16:1,2 to protect, and not betray the people of the Jews that should flee to them, because of the Assyrian army, Isa 16:3,4 and for this end gives a great character of the king of Judah, and assures them of the stability of his kingdom, Isa 16:5 but for their pride, wrath, and lying, they are threatened with destruction, and are represented as howling under it, Isa 16:6,7 because of the spoil of their cities, vineyards, and fields, so that they have no harvest, nor vintage, nor gathering of summer fruits, or joy on these accounts, Isa 16:8-10 for which even the prophet expresses a concern, Isa 16:11 and after having observed the application of the Moabites to their gods without success, Isa 16:12 the chapter is closed with an assurance of the certain ruin of Moab, and of the time when it should be, Isa 16:13,14.
