Charles Ellicott Commentary Isaiah 22:12

"And in that day did the Lord, Jehovah of hosts, call to weeping, and to mourning, and to baldness, and to girding with sackcloth:" — Isaiah 22:12 (ASV)

To weeping, and to mourning, and to baldness ... — National danger, Isaiah adds, should call to a national repentance in its outward manifestations, like the fast described in Joel 2. "Baldness," produced by the tearing of the hair in extreme grief, took its place naturally, with weeping and sackcloth, in those manifestations.
