Jesus invited Levi to be his disciple and refuted those who objected to his associating with such people.

Mark 2:13-17

13 Jesus left Capernaum town again and walked with his disciples alongside Galilee lake. A large crowd came to him. Then he taught them. 14 As he walked on further, he saw a man named Levi, whose other name was Matthew, and whose father’s name was Alpheus. He was sitting in his office where he collected taxes for the Roman government. Jesus said to him, “Come with me and become my disciple!” So he got up and went with Jesus.

15 Later, Jesus was eating a meal in Levi’s house. Many men who collected taxes and other people who were considered to be sinning regularly were eating with Jesus and his disciples. This was not surprising, for there were many people like this who were going everywhere with Jesus. 16 The men who taught the Jewish laws who were there and who were members of the Pharisee sect saw that Jesus was eating with men who collected taxes and others who were considered {whom they considered} to be sinners. So they said to his disciples, “◄It is disgusting that he eats with such disgusting men as those who collect taxes, and with other sinners!/Why is it that he eats with such disgusting men as those who collect taxes, and with other sinners?►” [RHQ] 17 After Jesus heard what they were saying, he said to the men who taught the Jewish laws, “People who consider that they are well do not seek a doctor. On the contrary, it is those who are sick who seek a doctor [MET]!” This he said to indicate that it was those who knew that they had sinned who were coming to him in order that he might help them spiritually. And he said, “I did not come to invite people who think that [IRO] they are righteous to come to me and turn from their sinful behavior. On the contrary, I came from heaven to invite people who know that they are sinners, in order that they might turn from their sins and come to me.”
