Question: Explain Isa. 25:12. "And the high fortress of thy walls hath he brought down, laid low, and brought to the ground, even to the dust." 1. Cf. v. 10: "In this mountain": 24:23; 25:6; Jehovah's holy mountain (11:9), "will the hand of Jehovah rest". It will settle there permanently. The helping and protecting hand of the Lord will rest in His holy city, continuing to care for His own at all times. 2. The abrupt introduction of judgment against Moab: nation known for its pride and arrogance which must be completely destroyed before anyone can share the salvation in Mt. Zion. Moab is characterized as very proud, arrogant, and boastful (16:6; Jer.48:29-30), holding Israel in derision, magnifying himself against Jehovah (Jer. 48:26,42), and holding the dignity of man in contempt (Amos 2:1; Zeph. 2:8,10). As a consequence, Moab shall be trodden down in his place. Before Moab (or people of any nation) can participate in salvation, the spirit of haughtiness against Jehovah and His people has to be destroyed. This appears to be the point of the prophecy. 3. Jehovah will lay low his pride (v.11). This verifies the proverb, "Pride goeth before destruction, And a haughty spirit before a fall" (Prov. 16:18).
