Albert Barnes Commentary Isaiah 25:10

"For in this mountain will the hand of Jehovah rest; and Moab shall be trodden down in his place, even as straw is trodden down in the water of the dung-hill." — Isaiah 25:10 (ASV)

For in this mountain - In Mount Zion.

Shall the hand of the Lord rest - "The hand" in the Scriptures is often used as the symbol of protection and defense. By the expression that the hand of Yahweh should REST on Mount Zion, it is probably meant that He would be its defender. His protection would not be withdrawn but would be permanent there. For an illustration of the phrase, see a similar use of the word "hand" as denoting protection, in Ezra 7:6, Ezra 7:28, Ezra 8:18, Ezra 8:22, Ezra 8:31, and Nehemiah 2:8.

And Moab - (For an account of Moab, see the notes at Isaiah 15:1-9 and Isaiah 16:1-14.) Moab here seems to be used in a general sense to denote the enemies of God. The declaration that it would be trodden down appears designed to indicate that the foes of God and His people would all be destroyed (compare the notes at Isaiah 34).

Under him - The Chaldee renders this, ‘In his own place.’ The phrase has the sense of ‘in his place’ in Exodus 16:29 and 2 Samuel 2:23. Here it may mean that Moab, or the enemies of God, would be trodden down and destroyed in their own land.

As straw is trodden down for the dunghill - As straw is left to lie in the yard where cattle lie, to be trodden down by them for the purpose of making manure. Lowth renders this:

‘As the straw is threshed under the wheels of the car.’

The Septuagint renders it in the same way. Lowth supposes that there has been an error in transcribing the Hebrew text, and that the former reading was מדכבה instead of מדמנה. But there is not the slightest evidence from the manuscripts that any such mistake has occurred. Nor is it necessary to suppose it. The image is one that is not uncommon in the Scriptures to denote the complete and disgraceful prostration of an enemy (2 Kings 9:37; Jeremiah 8:2; Jeremiah 9:22; Jeremiah 16:4; Jeremiah 25:33).
