Jesus explains to his disciples what he had taught
17 Jesus left the crowd of people and he went into a house. Then his disciples asked him to explain what he had taught.
18 Jesus said, ‘I am surprised that you too do not understand what I am saying. You should understand that food will not make people unclean. Food goes into a people's bodies from outside. 19 But food does not go into people's minds. It goes into their stomachs and then it passes out of their bodies.’
When Jesus said this, he was teaching that all foods are clean.
20 Jesus then said, ‘People become unclean because of what comes out from them, not because of what goes in. 21 Bad thoughts come from people's minds. As a result they do wrong things. They might have sex in wrong ways. They might rob somebody. They might kill somebody. They might have sex with another man's wife. 22 They may want too much for themselves. They may be cruel to other people. They might tell lies. They might live like wild animals. They may want things that other people have. They may speak bad things against other people. They might think that they themselves are very important. They might think in ways that are very silly.
23 All these wrong things begin inside people's minds and then come out. That is what makes them unclean.’
