In the course of time Kayin brought an offering to ADONAI from the produce of the soil;
and Hevel too brought from the firstborn of his sheep, including their fat. ADONAI accepted Hevel and his offering
but did not accept Kayin and his offering. Kayin was very angry, and his face fell.
ADONAI said to Kayin, "Why are you angry? Why so downcast?
If you are doing what is good, shouldn't you hold your head high? And if you don't do what is good, sin is crouching at the door - it wants you, but you can rule over it."
