The Ammonites, descendants of Lot through his younger daughter (Genesis 19:38), were a people frequently in conflict with the Israelites. The biblical prophecies against Ammon are found primarily in the books of Jeremiah, Ezekiel, and Amos. These prophecies address the judgment and destruction that would come upon Ammon due to their actions and attitudes towards Israel and Judah.

Jeremiah 49:1-6
In the book of Jeremiah, the prophecy against Ammon begins with a rhetorical question: "Does Israel have no sons? Is he without an heir? Why then has Milcom taken possession of Gad, and why do his people live in its cities?" (Jeremiah 49:1). This passage highlights the Ammonites' encroachment on Israelite territory, specifically the land of Gad. The prophecy foretells that the days are coming when the Lord will sound the battle cry against Rabbah of the Ammonites, leading to its desolation. The text promises that Israel will repossess its inheritance. The prophecy concludes with a note of hope, stating, "But afterward I will restore the captivity of the Ammonites," declares the LORD (Jeremiah 49:6).

Ezekiel 25:1-7
Ezekiel's prophecy against Ammon is part of a series of oracles against the nations. The Ammonites are condemned for their rejoicing over the desecration of the sanctuary, the desolation of the land of Israel, and the exile of the people of Judah. The Lord declares, "Because you clapped your hands and stomped your feet and rejoiced with all the malice of your heart against the land of Israel, therefore I will stretch out My hand against you and give you as plunder to the nations" (Ezekiel 25:6-7). The prophecy emphasizes that the judgment will lead to the recognition of the sovereignty of the Lord.

Amos 1:13-15
The book of Amos also contains a prophecy against Ammon, focusing on their violent actions. The Lord pronounces judgment on Ammon "because they ripped open the pregnant women of Gilead in order to enlarge their territory" (Amos 1:13). This brutal act is cited as the reason for divine retribution. The prophecy foretells that a fire will consume the walls of Rabbah, and the Ammonite king and his officials will go into exile.

Historical and Theological Context
The Ammonites were located east of the Jordan River, in what is now modern-day Jordan. Their capital was Rabbah, known today as Amman. Throughout biblical history, the Ammonites were often hostile towards Israel, engaging in various conflicts and alliances against them. The prophecies against Ammon reflect the broader theme of divine justice and the sovereignty of God over all nations. The Ammonites' actions against Israel and their celebration of Israel's misfortunes are met with divine judgment, emphasizing the moral and ethical standards expected by God.

These prophecies serve as a reminder of the consequences of enmity and injustice, as well as the hope of restoration and redemption, even for those who have opposed God's people.
