While Jesus is praying in a certain place, one of his disciples asks him to teach them to pray. Jesus gives the Lord's Prayer: hallowed be the Father's name, his kingdom come, give us each day our daily bread, forgive us our sins as we forgive those indebted to us, and lead us not into temptation. He then tells of a friend who bothers a neighbor at midnight for bread and receives what he needs because of his persistence. He urges them to ask, seek and knock, because the Father will give the Holy Spirit to those who ask, far more than a human father gives good gifts to his children.
Jesus casts out a demon that was mute, and some say he does it by Beelzebul, the prince of demons, while others ask for a sign from heaven. Jesus answers that a divided kingdom cannot stand, that if he casts out demons by the finger of God the kingdom of God has come, and that whoever is not with him is against him. A woman in the crowd blesses Jesus' mother, and he replies that those who hear the word of God and keep it are more blessed. To the generation seeking a sign, Jesus says it will receive only the sign of Jonah: the queen of the South and the men of Nineveh will condemn those who did not listen to one greater than Solomon and Jonah. He speaks of the lamp of the body: take care that the light in you is not darkness.
Invited to dine at a Pharisee's house, Jesus does not wash before the meal and his host is surprised. Jesus says they clean the outside of the cup, but inside they are full of greed and wickedness, and he pronounces woes on the Pharisees for tithing without justice, loving the best seats and being like hidden graves. He also accuses the lawyers of burdening others, of building tombs for the prophets their fathers killed, and of taking away the key of knowledge. The scribes and Pharisees begin to press him hard, lying in wait to catch him in something he says.
