"Is it lawful for a man to divorce his wife?" Jesus responds that they’re asking the wrong question and that they’re looking at the wrong Bible passage for the answer. They were arguing over a section from Deuteronomy that regulated divorce in order to protect people who were being victimized by a widespread, hard-hearted disregard for marriage. Jesus responds that instead of arguing over the wording of regulations for divorce, they should be paying attention to God’s definition of marriage. A man and a woman voluntarily enter into it, but God is also involved by defying the rules of mathematics and making 1+1=1. "Therefore what God has joined together, let no one separate."
