Albert Barnes 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)

Ammon and Moab, of common origin, whose lands had so often been interchanged, shall now share a common ruin. To the men of the east (Ezekiel 25:4) shall Moab with Ammon be given, that Ammon may be remembered no more, and judgment be executed on Moab.
