Isaiah 16 is a prophecy against Moab, a neighboring nation of Israel, that gives them advice and warns them of their approaching doom. Their advice is to send praise to the king of Judah, who is from the house of David, and to shelter the Jewish refugees who flee from the Assyrian invasion. A warning is that Moab will be destroyed because of their pride, wrath, and lying and that their cities, vineyards, and fields will be barren. The prophecy also conveys the concern of the prophet for the Moabites and the worthlessness of their heresy. The time of the fulfillment of the prophecy is specified as within three years. This is a continuation of the prophecy against Moab; in which the prophet gives good advice, but in case of arrogant neglect of it, which he foresaw, threatens with ruin, and fixes a time for it.

It reads in Isaiah 16:1-14 NIV
Send lambs as tribute to the ruler of the land, from Sela, across the desert, to the mount of Daughter Zion. Like fluttering birds pushed from the nest, so are the women of Moab at the fords of the Arnon. “Make up your mind,” Moab says. “Render a decision. Make your shadow like night, at high noon. Hide the fugitives, do not betray the refugees. Let the Moabite fugitives stay with you; be their shelter from the destroyer.” The oppressor will come to an end, and destruction will cease; the aggressor will vanish from the land. In love a throne will be established; in faithfulness, a man will sit on it, one from the house of David, one who in judging seeks justice and speeds the cause of righteousness. We have heard of Moab’s pride, how great is her arrogance! of her conceit, her pride, and her insolence; but her boasts are empty. Therefore the Moabites wail, they wail together for Moab. Lament and grieve for the raisin cakes of Kir Hareseth. The fields of Heshbon wither, the vines of Sibmah also. The rulers of the nations have trampled down the choicest vines, which once reached Jazer and spread toward the desert. Their shoots spread out and went as far as the sea. So I weep, as Jazer weeps, for the vines of Sibmah. Heshbon and Elealeh, I drench you with tears! The shouts of joy over your ripened fruit and over your harvests have been stilled. Joy and gladness are taken away from the orchards; no one sings or shouts in the vineyards; no one treads out wine at the presses, for I have put an end to the shouting. My heart laments for Moab like a harp, my inmost being for Kir Hareseth. When Moab appears at her high place, she only wears herself out; when she goes to her shrine to pray, it is to no avail. This is the word the Lord has already spoken concerning Moab. But now the Lord says: “Within three years, as a servant bound by contract would count them, Moab’s splendor and all her many people will be despised, and her survivors will be very few and feeble.”
