Know (sexually)
This can, of course, be a wonderful thing: It is essential for our journey to heaven, and is the reason for the holiness of marriage. But when the men represent falsity it can also be horrendously twisted, as in the attempted homosexual rape in Sodom (Genesis 19) and the rape of the concubine in Gibeah (Judges 19). In a general sense, men represent things of the intellect -- facts, ideas, knowledge, everything from the deepest truths to the most pernicious falsities about life and the Lord. Women in general represents things of affection -- desire, passion, caring, everything from the most exalted love for the Lord to the darkest hatred. When a man “knows” a woman in the Bible, then, it represents a joining together of those intellectual and affectionate faculties. “Know" is also often used in connection with virginity. A women who has “not known a man” represents the affection for truth, unsullied by falsity.
Revelation 21:1-5
1
I saw a new heaven and a new earth: for the first heaven and the first earth have passed away, and the sea is no more.
2
I saw the holy city, New Jerusalem, coming down out of heaven from God, prepared like a bride adorned for her husband.
3
I heard a loud voice out of heaven saying, "Behold, God's dwelling is with people, and he will dwell with them, and they will be his people, and God himself will be with them as their God.
4
He will wipe away from them every tear from their eyes. Death will be no more; neither will there be mourning, nor crying, nor pain, any more. The first things have passed away."
5
He who sits on the throne said, "Behold, I am making all things new." He said, "Write, for these words of God are faithful and true."
