Zephaniah 2:8 “I have heard the reproach of Moab, and the insults of the people of Ammon, with which they have reproached My people, and made arrogant threats against their borders. [9] Therefore, as I live,” says the Lord of hosts, the God of Israel, “Surely Moab shall be like Sodom, and the people of Ammon like Gomorrah–overrun with weeds and saltpits, and a perpetual desolation. The residue of My people shall plunder them, and the remnant of My people shall possess them.”
Moab is one of the incestual sons of Lot after he and his daughters fled Sodom, Genesis 19:37. Lot, being the son of Haran, was Abraham’s nephew, Genesis 11:31. Moab became father to the Moabites, cousins as it were to Israel. Yes there was no love between these peoples. Moab, in the book of Jeremiah, is called, “the people of Chemosh,” Jeremiah 48:46.
