The Woman's Seed

An interpretation of the Bible that Christians use to support their assertion that Isaiah 7:14 involves the following passage from Genesis:

Genesis 3:15 And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel. (KJV)

Which is referenced here:

Revelations 12:17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ. (KJV)

The point that Christian assert here is that the Lord is speaking here of the "seed of the woman." We all know that in the figurative language of the Bible, the man provides the "seed," as we see below:

Genesis 12:7 And the LORD appeared unto Abram, and said, Unto thy seed will I give this land: and there builded he an altar unto the LORD, who appeared unto him. (KJV)

So, given the fact that this "seed7quot; terminology should in theory be in reference to men only, we are left with a puzzle. Christian theology claims that Jesus was born of a virgin, therefore he would not have the seed of a man! Therefore, Genesis 3:15 is about Jesus' eternal struggle with the serpent, whom the Christian Bible says is Satan.

If we search the Bible, will we find facts corroborating this theory, or contradicting it?

Genesis 16:7 And the angel of the LORD found her by a fountain of water in the wilderness, by the fountain in the way to Shur. [8] And he said, Hagar, Sarai's maid, whence camest thou? and whither wilt thou go? And she said, I flee from the face of my mistress Sarai. [9] And the angel of the LORD said unto her, Return to thy mistress, and submit thyself under her hands. [10] And the angel of the LORD said unto her, I will multiply thy seed exceedingly, that it shall not be numbered for multitude. (KJV)

So, from this passage in Genesis, we see that the descendants of Hagar, Ishmael's mother, were called "seed," as well. Since neither chapter 1 of Matthew nor chapter 3 of Luke make the claim that Jesus is descended from Ishmael, we see that "seed" can be used allegorically for both the descendants of men and women, depending on the context.
