Charles Ellicott Commentary Isaiah 28:7

"And even these reel with wine, and stagger with strong drink; the priest and the prophet reel with strong drink, they are swallowed up of wine, they stagger with strong drink; they err in vision, they stumble in judgment." — Isaiah 28:7 (ASV)

But they also have erred through ... —Better, yet these also reel ... Isaiah acts on the method of Nathan when he said, “You are the man.” He has painted the drunkards of Ephraim; now he turns and paints in yet darker colours the drunkards of Judah. Priests were seen reeling to their services, prophets reeling in the very act of their counterfeit inspiration.

The threefold iteration of the word for “reel” emphasizes the scandals of the scene. The sins of the sons of Eli, those of which Micah (Isaiah 2:11) had spoken, were reproduced in all their enormity. The most loathsome features of their drunkenness are printed in Isaiah 28:8 with a boldness that is almost photographic. The prohibition of wine during the time when the priests were on duty (Leviticus 10:1–9) adds to the guilt represented in this way.
