Joel 1:13 - Joseph Benson’s Commentary on the Old and New Testaments

Gird yourselves Namely, with sackcloth; and lament, ye priests Because the meat-offerings and drink-offerings were cut off: see Joel 1:9. Lie all night in sackcloth Let those priests, whose turn it is to keep the night-watches in the temple, cover themselves with sackcloth, as is usual in times of the greatest calamity; and let them not put it off when they betake themselves to rest, but sleep in sackcloth instead of their ordinary garments.
