Jesus tells his disciples that stumbling blocks are bound to come, but woe to the one through whom they come! It would be better for him to have a millstone hung around his neck than to cause one of these little ones to stumble. He tells them to rebuke a brother who sins and forgive him if he repents, even if he sins seven times a day. The apostles ask him to increase their faith, and Jesus says that if they had faith like a mustard seed they could tell a sycamine tree to be planted in the sea. He then teaches that a servant who has worked all day does not expect special thanks: when he has done what was commanded, he should say he is an unworthy servant who has only done his duty.
On the way to Jerusalem, passing between Samaria and Galilee, ten lepers cry out from a distance for him to have mercy on them. Jesus tells them to go and show themselves to the priests, and as they go they are cleansed. One of them, a Samaritan, turns back praising God with a loud voice, falls at Jesus' feet and thanks him. Jesus asks about the other nine and says only this foreigner returned to give glory to God. He tells him to rise and go his way, his faith has made him well.
The Pharisees ask when the kingdom of God is coming. Jesus answers that it does not come with observable signs, and that the kingdom of God is in their midst. He tells the disciples not to follow those who say he is here or there: like lightning that flashes from one end to the other, so will the Son of Man be in his day. First he must suffer much and be rejected. He compares his coming with the days of Noah and Lot, when life went on as usual until judgment came. He tells them to remember Lot's wife and not to cling to life; one will be taken and the other left. When they ask where, Jesus answers with an image: where the corpse is, there the vultures will gather.
