1. The sin which they had been most notoriously guilty of, and for which God now reckoned with them, was pride. It is mentioned six times, v. 29. We have all heard of the pride of Moab; his neighbours took notice of it; it has testified to his face, as Israel's did; he is exceedingly proud, and grows worse and worse. Observe his loftiness, his arrogancy, his pride, his haughtiness; the multiplying of words to the same purport intimates in how many instances he discovered his pride, and how offensive it was both to God and man. It was charged upon them Isa. xvi. 6, but here it is expressed more largely that there. Since then they had been under humbling providences, and yet were unhumbled; nay, they grew more arrogant and haughty, which plainly marked them for that utter destruction of which pride is the forerunner. Two instances are here given of the pride of Moab:— (1.) He had conducted himself insolently towards God. He must be brought down with shame (v. 26), for he has magnified himself against the Lord; and again (v. 42), he shall be destroyed from being a people, for this very reason. The Moabites preferred Chemosh before Jehovah, and thought themselves a match for the God of Israel, whom they set at defiance. (2.) He had conducted himself scornfully towards Israel, particularly in their late troubles; therefore Moab shall fall into the same troubles; into the same hands, and be a derision, for Israel was a derision to him, v. 26, 27. The generality of the Moabites, when they heard of the calamities and desolations of their neighbours the Jews, instead of lamenting them, rejoiced in them, they skipped for joy. Many, in such a case, entertain in their minds a secret pleasure at the fall of those they had a dislike to, who yet have so much discretion as to conceal it; it is so invidious a thing. But the Moabites industriously proclaimed their joy, and avowed the enmity they had to Israel, triumphing over every Israelite they met with in distress and laughing at him, which was as inhuman as it was impious and an impudent affront both to man, whose nature they were of, and to God, whose name they were called by. Note, Those that deride others in distress will justly and certainly, sooner or later, come into distress themselves, and be had in derision. Those that are glad at calamities, especially the calamities of God's church, shall not long go unpunished.
