Mark 7:4-5

4When they come from the market place, they always wash themselves carefully. Unless they do this, they do not eat anything. Their leaders also gave them rules about how they should wash cups, pots and metal bowls.)

5The Pharisees and the teachers of God's Law said to Jesus, ‘Your disciples do not obey the things that our leaders taught many years ago. Your disciples have not washed their hands in the right way. They are eating their food with unclean hands. That is not right.’
