Who was Moab?
Moab (Isa. 15:1–16:14)
The Moabites were the product of Lot’s incestuous union with his daughter (Gen. 19:30–38) and were the avowed enemies of the Jews (Num. 25; 31; Deut. 23:3).
The plight of Moab (Isa. 15:1–9). Within three years (16:14), this prophecy against Moab would be fulfilled with great national lamentation. At least fourteen different references to lamentation occur in this chapter: weeping, wailing, baldness, sackcloth, crying out, etc. The people fled to their temples and prayed to their gods, but to no avail (15:2, NIV). Even a day of national humiliation did not stop Assyria from invading Moab and ravaging the land. Advancing armies often stopped up the springs and watercourses, and left the land in desolation (vv. 6–7). Where there was water in Moab, it was stained with blood, so great was the carnage (v. 9). How could the weak Moabites ever hope to defeat the great Assyrian lion?
The plea of Moab (Isa. 16:1–5). The one place the Assyrians could not conquer was Jerusalem (10:24–34). Though the Assyrian army entered the kingdom of Judah and did a great deal of damage to the land, it could not capture Jerusalem (chaps. 36–37). However, instead of fleeing to Mt. Zion, the Moabite fugitives fled south to the fords of the Arnon River and the “rock city” of Sela in Edom.
From Sela, the fugitives sent an appeal to the king of Judah to give them asylum from the enemy. But Isaiah warned them that it would take more than a request: They would need to submit to the king of Judah, which meant acknowledging the God of Judah. On that day, sending animals to a ruler was a form of paying tribute (2 Kings 3:4). Moab begged the leaders of Judah to give them refuge from the enemy, like a protecting rock on a hot day (16:3–4; see 32:1–2).
Isaiah was not impressed with the appeals of the Moabites. He called the Moabites extortioners, spoilers, and oppressors, and announced that the nation was destined to be destroyed (16:4). Why? Because they wanted Judah’s help, but they did not want Judah’s God. Verse 5 is definitely a messianic promise, pointing to the day when Messiah will reign in righteousness and mercy on David’s throne. But Moab would not submit; they wanted deliverance on their own terms.
The pride of Moab (Isa. 16:6–14). We can understand the pride of a city like Babylon (14:12–14), but what did the tiny nation of Moab have to boast about? Their pride kept them from submitting to Judah, and this led to their defeat. Their boasting would turn into wailing and their songs into funeral dirges. Moab would become like a vineyard trampled down and a fruitful field left unharvested. Isaiah 16:9–11 describes the prophet’s grief—and the Lord’s grief—over the destruction of Moab. “I have no pleasure in the death of the wicked” (Ezek. 33:11). Isaiah could have rejoiced at the destruction of an old enemy, but instead, he wept (Prov. 24:17–18).
