Matthew 5:20-22; Matthew 5:27-28

20 For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven. 21 “You have heard that it was said to the people long ago, ‘You shall not murder,and anyone who murders will be subject to judgment.’ 22 But I tell you that anyone who is angry with a brother or sisterwill be subject to judgment. Again, anyone who says to a brother or sister, ‘Raca,’is answerable to the court. And anyone who says, ‘You fool!’ will be in danger of the fire of hell.
27 “You have heard that it was said, ‘You shall not commit adultery.’ 28 But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.
