God will "smite with a scab the crown of the head of the daughters of Zion" and "will discover their secret parts" since he
doesn't like the way they dress and walk. 3:16-17
Isaiah has sex with a prophetess who conceives and bears a son. (You weren't expecting a daughter, were you?) God then
tells Isaiah to call his name Mathershalalhashbaz. (It has a nice ring to it, doesn't it?) 8:3
God tells Isaiah to take off all his clothes and to wander about completely naked for three years as a "sign and a wonder."
In this way he will be just like the Egyptian captives who will walk about naked "with their buttocks uncovered."
Tyre "shall commit fornication with all the kingdoms of the world," and her hire shall be holiness to the Lord."
