Charles Ellicott Commentary Joel 1:5

"Awake, ye drunkards, and weep; and wail, all ye drinkers of wine, because of the sweet wine; for it is cut off from your mouth." — Joel 1:5 (ASV)

Awake, ye drunkards— i.e., awake from such an insensibility as wine causes. The people failed to see the hand of God in the terrible calamity, like an acted parable, of the locusts. Insensate, as the revellers in the halls of Belshazzar, they carried on their feasting even while the enemies were at the city gates.

It is cut off from your mouth. —Either joy and gladness, as given in the Septuagint, or the means of indulgence have been suddenly taken away.
