76:2.2

Now, in those days it was customary to make offerings to the priesthood of the things at hand. Herders would bring of their flocks, farmers of the fruits of the fields; and in accordance with this custom, Cain and Abel likewise made periodic offerings to the priests.

In vain did Cain appeal to the traditions of the first Eden, to the former preference for the fruits of the fields. But this Abel would not allow, and he taunted his older brother in his discomfiture.
