Jamieson, Fausset and Brown on Ezekiel 23:23

23. Pekod, &c.--(Jr 50:21). Not a geographical name, but descriptive of Babylon. "Visitation," peculiarly the land of "judgment"; in a double sense: actively, the inflicter of judgment on Judah; passively, as about to be afterwards herself the object of judgment.

Shoa ... Koa--"rich ... noble"; descriptive of Babylon in her prosperity, having all the world's wealth and dignity at her disposal. Maurer suggests that, as descriptive appellatives are subjoined to the proper name, "all the Assyrians" in the second hemistich of the verse (as the verse ought to be divided at "Koa"), so Pekod, Shoa, and Koa must be appellatives descriptive of "The Babylonians and ... Chaldeans" in the first hemistich; "Pekod" meaning "prefects"; Shoa ... Koa, "rich ... princely."

desirable young men--strong irony. Alluding to Eze 23:12, these "desirable young men" whom thou didst so "dote upon" for their manly vigor of appearance, shall by that very vigor be the better able to chastise thee.
