'Unveiled' in the Bible

About that time Jesus exclaimed, "I heartily praise Thee, Father, Lord of Heaven and of earth, that Thou hast hidden these things from sages and men of discernment, and hast unveiled them to babes.

in order that the words of Isaiah the Prophet might be fulfilled, "Lord, who has believed our preaching? And the arm of the Lord--to whom has it been unveiled?"

Judge of this for your own selves: is it seemly for a woman to pray to God when she is unveiled?

And all of us, with unveiled faces, reflecting like bright mirrors the glory of the Lord, are being transformed into the same likeness, from one degree of radiant holiness to another, even as derived from the Lord the Spirit.
