Genesis 4:1-2. And Adam knew Eve his wife; and she conceived and bare Cain, and said, I have gotten a man from the Lord. And she again bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground.

The birth of children brings joy to the parents. Eve must be very joyous for her generative power as part of divine power.

“Yahweh formed man; I have formed the second man. Abel was a ‘keeper’; Cain was a ‘tiller’, think about that (Adapted).

Why are you angry at God, be thankful.
