Jesus quotes Deuteronomy and Leviticus to summarise the Law, confounds the religious leaders with a question about whose son the messiah might be, then insults the Pharisees and religious leaders again: Mark 12:28–34; Matthew 22:34–40; Mark 12:35–37; Matthew 22:41–46; Luke 20:41–44; Mark 12:38–40; Matthew 23:1–12; Luke 20:45–47; Matthew 23:13–39; Mark 12:41–44; Luke 21:1–4
What are the entire law and all the demands of the prophets based on? Jesus said it’s this:
Matthew 22:37-39 You must love the Lord your God with all your heart, all your soul, and all your mind.’ A second is equally important: ‘Love your neighbor as yourself.’
It’s no surprise. Moses had said much the same thing when he presented the ten commandments as a covenant between God and the Israelites, and later, when he called them to obey the Lord and again, when urging them to be holy.
