Continuing in the book of Adam’s generations we saw that Enoch walked with God after he had begotten Methushelah and find Methushelah bringing Lemech (Lámek/Lamech) the father of Noah on this world. The account ends with Noah having Shem, Ham, and Yefet/Japeth.
Going from Enosh, the son of Seth and grandson of Adam, we go up to another Enoch in the family tree, namely the son of Jared and grandson of Mahalalel. We know those descendants of Adam had come to recognise the Divine Creator as their God to call upon His Name.
Elohim had blessed the human beings He had created and allowed them to have children. That way A'dham became the father "of a son" in his own likeness, "after" his own image. We were not told this about Cain and Abel simply because the text did not wish to discuss them at length. In this chapter 5 Moses goes straight to the third son of Adam, Enosh. It is noted that from that time the people started to call upon the Name of Jehovah God.
The genealogy of Adam gives us a picture how from those being created in the image of God, were born new creatures. Male and female were created by the Only One God, Who blessed them and gave them the possibility to bring forth new blood, so that the purpose of God, to fill the world could be fulfilled.
The fifth chapter of the first book of the Pentateuch brings us the accounting of mankind. Moses gives an idea how the Children of God came one after the other on earth to play their role in history.
Adam and Eve got many children and their children also gave birth to several children, so that the world was populated as God had told them.
Kayin of Cain is more concerned what would happen to him after he did that terrible act (of killing his brother). God, instead of making an end to Cain's life straight ahead, left Cain alive as an even more poignant sign of sin.
What the Scriptures tells us about how God reacted on Kayn (Cain) his act of offering and killing his brother
We come now to the position that the 1st man had relations with his wife Eve, and she conceived and gave birth to Cain, who when older brought offerings to please God.
The Word of God tells us how the first living souls became tricked by their own wrong thoughts and fell for the pleasing of their eyes and by their disobedience to God got punishments over them and got being banished from the Garden of Eden.
In the second chapter of the Bereshith light is shed on the day that יהוה Elohim made earth and heavens and created a beautiful Royal Garden where man, made in the image of God, could live in peace, with the animals, to which he receives rulership (not ownership over the earth).
The Bible opens with the story of the beginning of everything, presenting the six periods of development (six days of creation) and the final period of establishment or rest.
