Ezekiel 25:1-5 (ESV)
Prophecy Against Ammon
The word of the LORD came to me: “Son of man, set your face toward the Ammonites and prophesy against them. Say to the Ammonites, Hear the word of the Lord GOD: Thus says the Lord GOD, Because you said, ‘Aha!’ over my sanctuary when it was profaned, and over the land of Israel when it was made desolate, and over the house of Judah when they went into exile, therefore behold, I am handing you over to the people of the East for a possession, and they shall set their encampments among you and make their dwellings in your midst. They shall eat your fruit, and they shall drink your milk. I will make Rabbah a pasture for camels and Ammon a fold for flocks. Then you will know that I am the LORD.
God is coming against Ammon because of how they treated His people. Note the following:

Prophecy Against Tyre
In the eleventh year, on the first day of the month, the word of the LORD came to me: “Son of man, because Tyre said concerning Jerusalem, ‘Aha, the gate of the peoples is broken; it has swung open to me. I shall be replenished, now that she is laid waste,’
God takes vengeance on those who mistreat His people. We are not to take vengeance. He will.
Romans 12:17-19 (ESV)
Repay no one evil for evil, but give thought to do what is honorable in the sight of all. If possible, so far as it depends on you, live peaceably with all. Beloved, never avenge yourselves, but leave it to the wrath of God, for it is written, “Vengeance is mine, I will repay, says the Lord.”
