Isaiah 15 has the prophet talking about the people of Moab. The founder of the people of Moab was the son born of the incestuous relationship between Lot and one of his daughters, when his daughters made Lot drunk, after the destruction of Sodom and Gomorrah (Genesis 19:30-38). The Moabites settled in the plains to the south-east of Israel, in what is modern-day Jordan. These were enemies of Israel who had from time to time had Israel under oppression. They were enemies.
During the time of Saul and David, Israel established a firm control over Moab, but later kings of Israel were not always able to keep them under Israeli dominance. At the same time, there was a Moabite connection with Israel. First, they were related to Israel because Lot was Abraham’s nephew. Because of this, God told Israel in Deuteronomy 2:9 that they were not to destroy Moab and take their land. As well, David, Israel’s greatest king, was one-quarter Moabite. His paternal grandmother Ruth was from Moab, and David entrusted his father and mother to the protection of the king of Moab when he was a fugitive from Saul. So there is some sadness with the coming destruction of the Moabites.
Scripture tells us the Moabite will flee “to the high places to weep”. They run to their pagan temple and worthless gods for protection and mourning to no avail. The destruction is coming, and nothing will stop it. They try to deal with their distress through their own human actions. “On every head is baldness; every beard is shorn; in the streets they wear sackcloth; on the housetops and in the squares everyone wails and melts in tears”. But the bottom line is destruction is coming and they will not escape it.
God’s judgment is severe. The plains of Moab were rich grazing land. But now, not so much. “The waters….are a desolation; the grass is withered, the vegetation fails, the greenery is no more. Therefore the abundance they have gained and what they have laid up they carry away”. Their pain in the midst of judgment is evident to all. Everyone around the borders of Moab sees God’s judgment against them. God’s going to finish His judgment on them, no matter where they run and try to hide. He is never thwarted in His plan.
