The following is based on Genesis 3:21-24; Genesis 4; 1 Chronicles 1:1; Luke 3:38
According to the Torah — the Bible’s Old Testament — the first man (Adam) and the first woman (Eve) disrespected the Lord God and chose to obey “the serpent” — Satan — rather than their Creator. That one act of disobedience granted the evil one authority over those two individuals, as well as EVERY HUMAN DESCENDANT that would result from their union.
But God still loved them. Still longed for RELATIONSHIP with them. And He demonstrated that love through two basic acts of protection and provision:
First, “Adonai, God, made garments of skin for Adam and his wife and clothed them” (Genesis 3:21, The Complete Jewish Bible). This was the first time animals were killed for the purpose of protecting physical, human bodies from the harsh conditions that existed beyond the pristine boundaries which God had assigned for Adam and Eve to call home.
(When “sin” was allowed to contaminate Adam and Eve’s perfect environment, their loving Father had to take yet another drastic measure to ensure their spiritual protection.)
Second, “Adonai, God, said, ‘See, the man has become like one of us [the introduction of God as Father, Son and Holy Spirit combined], knowing good and evil. Now, to prevent his putting out his hand and taking also from the tree of life, eating, and living forever [trapped in a fallen world] — ‘ therefore Adonai, God, sent him out of the garden of ‘Eden to cultivate the ground from which he was taken. So he drove the man out, and he placed at the east of the garden of ‘Eden the k’ruvim [cherubs beyond human comprehension] and a flaming sword which turned in every direction to guard the way to the tree of life.” (Genesis 3:22-24, The Complete Jewish Bible)
On the outside of perfection, Adam had sexual relations with his wife (Havah), and they produced two sons — Cain (Kayin), the older son, farmed the soil. And Abel (Hevel), who kept the sheep. The passage suggests that Cain’s heart was filled with EVIL, whereas Abel’s heart was filled with GOOD. Cain rebelled against God and killed his brother Abel in a fit of jealousy and anger. Then he lied when the Lord God asked him what he had done. You can read the written account in Genesis 4. This was the first time that murder was recorded in the Old Testament. God responded by banishing Cain from RELATIONSHIP with his parents and commanding that he would be “a fugitive” — a restless wanderer on the earth.
But God still loved Cain and provided a “mark” (New International Version) or “sign” (Complete Jewish Bible) on his body so that “no one who found him would kill him.”
(Herein lies a mystery: Where did the other people come from? How were they made? When did they appear on the earth? … I don’t feel qualified to comment on this, but you can find MANY other writers who have “set in stone” opinions about it!)
Once again, God showed compassion toward Adam and Eve and blessed them with a third son: “Adam again had sexual relations with his wife, and she gave birth to a son whom she named Shet — or Seth — [meaning granted], ‘For God has granted me another seed in place of Hevel, since Kayin killed him.’ To Shet too was born a son, whom he called Enosh. That is when people began to call on the name of Adonai.” (Genesis 4:25-26, CJB)
The birth of Seth signaled an era of hope for mankind in a fallen world. Generations later, another birth would also be welcomed as a hopeful and joyful SIGN … the arrival of Yeshua — Jesus. A direct descendant of Seth…. God in the flesh.
