Isaiah 25:10
10. rest—as its permanent protector; on "hand" in this sense; compare Ezr 7:6, 28.
Moab—while Israel is being protected, the foe is destroyed; Moab is the representative of all the foes of God's people. under him—Rather, "in his own place" or "country" (Ex 10:23; 16:29). for the dunghill—Rather, "in the water of the dung heap," in which straw was trodden to make it manure (Ps 83:10). HORSLEY translates either, "in the waters of Madmenah," namely, for the making of bricks; or as the Septuagint, "as the threshing-floor is trampled by the corn-drag" (see Margin; Mic 4:11-13). Jeremiah 48:29-30
29. pride— (Isa 16:6, 7). Moab was the trumpeter of his own fame. Jeremiah adds "loftiness and arrogancy" to Isaiah's picture, so that Moab had not only not been bettered by the chastisement previously endured as foretold by Isaiah, but had even become worse; so that his guilt, and therefore his sentence of punishment, are increased now. Six times Moab's pride (or the synonyms) are mentioned, to show the exceeding hatefulness of his sin.
30. I know—Moab's "proud arrogancy" (Jer 48:29) or "wrath," against My people, is not unknown to Me.
it shall not be so—The result shall not be so as he thinks: his lies shall not so effect what he aims at by them. CALVIN translates, "his lies are not right (that is, his vauntings are vain because God will not give them effect); they shall not do so" as they project in their minds, for God will set at naught their plans. Zephaniah 2:8
8. I have heard—A seasonable consolation to Judah when wantonly assailed by Moab and Ammon with impunity: God saith, "I have heard it all, though I might seem to men not to have observed it because I did not immediately inflict punishment."
magnified themselves—acted haughtily, invading the territory of Judah (Jer 48:29; 49:1; compare Zep 2:10; Ps 35:26; Ob 12).
