Paul’s point was that women should be modestly veiled in public worship. Paul then gives four reasons why:
1.) Refusal to adhere to modesty dishonors their husband.
2.) Its shamefully immodest, like a woman having her hair sheered or shaven (penalty for an adulterous woman).
3.) Rebellion brings judgment as we see with the angels that rebelled.
4.) Even nature teaches that a woman should be veiled because it has given her hair for a covering.
