@Knittinggrace Paul explains how much more glorious the New Covenant is and how different the outward signs are. Our faces aren't glowing, even though every servant of the Word shines brighter in this world than Moses. No more veils necessary. Everyone who is in Christ can behold the full glory of God through faith in Him.

BTW: there is a command for women to cover their head, different topic, but that symbolises obedience towards her headship, not hiding ones glory...
