Ellicott's Commentary for English Readers
(4) To the men of the east.—Literally, sons of the east, i.e., the various nomadic tribes inhabiting the Eastern deserts, who occupy the country to this day. They are described as its possessors, not its conquerors; the conquest was effected by Nebuchadnezzar. In Ezekiel 21:20-23 he was represented as hesitating whether to attack first Judah or Ammon, and determined to the former by the Divine direction; in this attack some of the Ammonites joined his army, but he nevertheless afterwards carried out his purpose and desolated their country. (See Ezekiel 21:28.)
Benson Commentary
Ezekiel 25:4-7. Behold, I will deliver thee to the men of the east — That is, to the Chaldeans, whose country lay east of the Ammonites. This people was accordingly conquered and subdued by the Chaldeans, about five years after the destruction of Jerusalem.
Barnes' Notes on the Bible
Men of the east - The wild wandering Arabs who should come in afterward upon the ruined land. The name was a common term for the nomadic tribes of the desert.
Jamieson-Fausset-Brown Bible Commentary
4. men of … east—literally, "children of the East," the nomad tribes of Arabia-Deserta, east of the Jordan and the Dead Sea.
Matthew Poole's Commentary
To the men of the East; the Medes and Persians, say some; the Babylonians, say others, but this suits not well with geography; Arabians, say others, associates of Nehuchadnezzar, who, it is likely, recompensed their labour and service with giving them this country when it was conquered, as it was five years after the desolation of Jerusalem.
Gill's Exposition of the Entire Bible
Behold, therefore, I will deliver thee to the men of the east for a possession,.... The Chaldeans and Syrians, which were on the east side, as Jarchi; or the Medes and Persians, as Kimchi, which lay more eastward; or it may be the Arabians, who are commonly called the men of the east; who were a part of Nebuchadnezzar's army, and whom he might reward with this country, when taken by him; for this prophecy, according to Josephus (q), was fulfilled five years after the destruction of Jerusalem.
Geneva Study Bible
To the Babylonians.
Cambridge Bible for Schools and Colleges

Pulpit Commentary
Verses 4, 5. - The men of the east; Hebrew, children of the east. The name is applied in Genesis 29:1; 1 Kings 4:30; Job 1:3; Judges 6:3, 33; Judges 7:12; Judges 8:10, to the nomadic tribes, Midianites and others, which roamed to and fro in the wilderness east of Ammon and Moab, after the manner of the modern Bedouins, with their sheep and camels, and were looked upon as descendants of Ishmael.
