Esau and Cain faced somewhat similar circumstances. Both were firstborn sons. Both were “passed over” by the LORD in favor of the younger brother. Both became enraged and sought revenge.
The LORD’s words to Cain would also be appropriate for Esau: “Why are you so angry? Why do you look so dejected? You will be accepted if you do what is right. But if you refuse to do what is right, then watch out! Sin is crouching at the door, eager to control you.”
Cain refused to do what was right, and murdered his brother. It was his choice. And now Esau, despite the “blessing” just received from his father, must choose.
The God of Cain and Abel, the God of Esau and the God of Jacob is the same God.
