Genesis 3:15 teaches the truth about what happened in the Garden; it exposes what Satan did to Eve as well as exposing God's fierce reaction to it. Christ, in the New Testament, further documents this fist sin for Jamie and you but before going there, a parting look at Genesis 3:15 KJV:
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.
Satan's seed impregnated Eve and while failing to block the seed line that Christ was to come, started a second bloodline, the Kenite bloodline.
Recalling that Noah was ordered to take two of every flesh, this second bloodline also made it through the flood; they show
themselves in 1 Chron 2:55 KJV:
And the families of the scribes which dwelt at Jabez;
the Tirathites, the Shimeathites, and Suchathites. These are the Kenites that came of Hemath, the father of the house of Rechab.
You find the Kenites here in a chapter set aside for Judah's bloodline only and when trying to come up with a reason for this to happen, only one comes to mind:
Working with the pen was a primary occupation for them and being scribes presented them ample opportunity to
include themselves in the verse translated here.
Perhaps you recall Christ warning of this threat in Rev 2:9 KJV and 3:9 KJV when He exposed them lying about their identity by claiming to be Jews?
Rev 2:9 KJV I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.
Rev 3:9 KJV Behold, I will make them of the synagogue of
Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.
Other places in the bible expose Satan's bloodline but none better than the parable of the Tares found in Matthew 13: 24-30 KJV:
Another parable put he forth unto them, saying, The kingdom of heaven is likened unto a man which sowed good seed in his field:  But while men slept, his enemy came and sowed tares among the wheat, and went his way.  But when the blade was sprung up, and brought forth fruit, then appeared the tares also.  So the servants of the householder came and said unto him, Sir, didst not thou sow good seed in thy field? From whence then hath it tares?  He said unto them, An enemy hath done this. The servants said unto him, Wilt thou then that we go and gather them up?  But he said, Nay; lest while ye gather
up the tares, ye root up also the wheat with them.  Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them; but gather the wheat into my barn.
This parable confused disciples and in Matthew 13:36 KJV they asked Christ
