As for Moab and Ammon, according to Jewish historian Josephus, in the fifth year after the fall of Jerusalem, the Babylonians waged war on them and conquered them. They subsequently ceased to exist, as prophesied.

15. How would Jehovah humiliate the gods of nations who had put on great airs against his people?

¹⁵ Psalm 83 mentions a number of nations, including Moab, Ammon, and Assyria, who put on great airs against Israel, and braggingly stated: “Come and let us efface them from being a nation, that the name of Israel may be remembered no more.” (Psalm 83:4) The prophet Zephaniah courageously announced that all these haughty nations and their gods would be humiliated by Jehovah of armies. “This is what they will have instead of their pride, because they reproached and kept putting on great airs against the people of Jehovah of armies. Jehovah will be fear-inspiring against them; for he will certainly emaciate all the gods of the earth, and people will bow down to him, each one from his place, all the islands of the nations.”—Zephaniah 2:10, 11.

“‘I have heard the reproach by Moab and the abusive words of the sons of Ammon, with which they have reproached my people and kept putting on great airs against their territory.

14. What evidence is there that foreign nations ‘put on great airs’ against the Israelites and their God, Jehovah?

¹⁴ Moab and Ammon were Israel’s traditional enemies. (Compare Judges 3:12-14.) The Moabite Stone, in the Louvre Museum in Paris, bears an inscription containing a boastful statement by Moabite King Mesha. He proudly relates his taking several Israelite cities with the help of his god Chemosh. (2 Kings 1:1) Jeremiah, a contemporary of Zephaniah, spoke of the Ammonites’ occupying the Israelite territory of Gad in the name of their god Malcam. (Jeremiah 49:1)
