Isaiah 25:9-12. “And it shall be said in that day, Lo, this is our God; we have waited for Him, and He will save us: this is the Lord; we have waited for Him. We will be glad and rejoice in His salvation. For in this mountain shall the hand of the Lord rest, and Moab shall be trodden down under Him, even as straw is trodden down for the dunghill. And He shall spread forth His hands in the midst of them, as he that swimmeth spreadeth forth his hands to swim: and he shall bring down their pride together with the spoils of their hands. And the fortress of the high fort of thy walls shall he bring down, lay low, and bring to the ground, even to the dust.”
Remember, in that day refers to the Millenial Reign of Jesus Christ. In this mountain is Mount Zion.
These four verses give a snapshot of how things will be in the Millenium. Israels’ enemies will be defeated. Not just defeated, but completely subjugated. Moab is mentioned here. It is a next-door neighbor to Israel, and in the Millenium it will serve Israel (Is. 11:14; 16: 1-5 ).
Israel will finally, as a nation, recognize that Jesus Christ is Messiah. They will turn their hearts back to Him, and the nation will flourish.
The hand of the Lord denotes His power, deliverance, and protection over His people (Ezra 7:6, 28; Neh. 2:8; Acts 4:30; 11:21). I think the picture of God defeating Israel’s enemies is so interesting: He will move His hands like a man swimming, easily moving through the water, easily defeating His enemies; and destroying their strong walls and fortresses, bringing them to the dust of the ground.
