John Gill Commentary Ezekiel 25:10

"unto the children of the east, [to go] against the children of Ammon; and I will give them for a possession, that the children of Ammon may not be remembered among the nations." — Ezekiel 25:10 (ASV)

Unto the men of the east with the Ammonites, and I will give
them in possession
Or, "against the Ammonites", as the Targum; that is, way should be made for the same people of the east, the Chaldeans or Arabians, that came against the Ammonites and destroyed them, to enter into the land of Moab and possess it, as they had done the land of Ammon: that the Ammonites may not be remembered among the nations :
the name of that people, which is entirely lost; and Moab likewise, which underwent the same fate.
