1. Matthew 19:6
"So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate."
Jesus confronts the Pharisaic debate between liberal divorce interpretation (Hillel school) and conservative view (Shammai school) by returning to God's original design. His declaration "what God has joined together, let no one separate" emphasizes that marriage creates a divine union - "two people become one flesh, one person, in the eyes of God." While acknowledging Moses' concession "because of the hardness of your hearts," Jesus reaffirms that "from the beginning it was not so." Divorce represents human sinfulness and "hardness of heart" - sometimes in the offending party who refuses reconciliation, sometimes in the offended party who won't forgive, often in both. Though Jesus permits divorce due to human frailty, He consistently points to God's intention for permanent covenant marriage that reflects divine faithfulness (BibleHub Commentaries).
