The first mention of bitterness in the Bible was in a son: Esau, the child of Isaac and Rebekah. When he felt he had been done wrong, Esau cried out with a “bitter cry.”
Esau wound up rejecting the grace of God and becoming a profane fornicator. It is like God was saying to all parents: Protect your children from becoming bitter.
