In the story of Kayin and Hevel we come to hear to what jealousy and envy can lead.
Bereshith 4 shows us what can go wrong when we have no good intentions and when our heart is not pure and honest in our actions.
It is not about a Devil’s Delusion but about man's delusion and human escape from his own responsible choices.
In the second and third chapter of the Bereshith (the book of the beginning) we find that God, Who had made man in His image, brought a helper for the ish or man so that they could live together in a bond of union, related to the other living beings and to the Most High Elohim, in a state we now call marriage.
Man knew that The Word of God brought life and order and got their mind wondering if they could not become as wise and mighty as God. The inner voice of man or the nachash is of self-esteem and brings deception when allowing oneself to be carried away by the temptation, falling into trickery, treachery,and insincerity.
