Albert Barnes Commentary Ezekiel 34:2

"Son of man, prophesy against the shepherds of Israel, prophesy, and say unto them, even to the shepherds, Thus saith the Lord Jehovah: Woe unto the shepherds of Israel that do feed themselves! should not the shepherds feed the sheep?" — Ezekiel 34:2 (ASV)

Shepherds - Not priests or prophets, but rulers and kings (see the Jeremiah 2:8 note). The most ancient title for “ruler” is a monogram that occurs on the oldest monuments discovered in the cuneiform character. In the Assyrian language it became riu (compare Hebrew רעה râ‛âh = shepherd). In the traditions of Berosus we find that Alorus, the first king in the world, received from the Divinity the title of Shepherd. The title, as well as the monogram, was preserved to the latest times of the Assyrian monarchy.

While the distress and misery of the people daily increased, the last kings of Judah exacted more and more from their subjects and lavished more and more on personal luxury and show.
