Matthew Poole and continuators on Isaiah 22:12

12 And in that day did the Lord GOD of hosts call to weeping, and to mourning; and to baldness , and to girding with saccloth.

Invite and oblige them by the Course of his Providence, and require this by the Precepts requiring these things in such Times and Conditions.

To make themselves bald, by plucking or shaving off the Hair of their Heads, as was usual in great Sorrows, as Ezra 9. 3. Iob 1. 20. Mic. 1. 16▪ although it was forbidden in case of the Death of Relations, for a special Reason; of which see on Levit. 19. 27, 28. & 21. 5.
