This passage of Scripture lifts up the family of Esau in great detail. It shares who the progeny of Esau was. His family is blessed, just as Abraham had promised he would be. Why would this passage be included, though? Israel was the chosen son of promise to bring about the fulfillment of the covenant. It is here because God’s faithfulness is true. God blesses those who believe in Him. Esau heard his mother and father say that they did not want their sons to marry Canaanite women, so he married a woman from his father’s family. He stayed with Isaac, even though he was spurned by his mother and lost his blessing from his father.
Esau was faithful and God made a powerful nation of him as well, in spite of his position in the covenant. Because God is faithful. God…is…faithful!
