Hebrews 12:17

17 As you know, after that, he still wanted to receive those good things from his father. He wanted his father to ask God to bless him. But his father refused to do that. Esau cried very much when he asked his father to give him those good things. But there was no way that Esau could change what he had done.

12:16Esau was Isaac's first son. The oldest son in a family was very important. He received the biggest part of his father's land and money when his father died. Also, the father asked God to bless that son and give him good things. But Esau gave away all these things to his brother, Jacob. See Genesis 25:29-34; 27:30-41.
