 But how do you define adultery? What really is adultery? You say, honor your father and your mother, but whatever we could have given to them is devoted to God, the Pharisees said. And so we can't really help our parents out. We can't really honor them. If you can imagine it, religious people, the religious people in Jesus's day had constructed very clever reasons, religious reasons for why they didn't have to obey God's word.
