Jesus exposes the hypocrisy of the Pharisees 'from Jerusalem' in this text. They charge Jesus of breaking the 'tradition of the elders' and Jesus reveals that they break God's great command to honor mother and father by caring for them in their golden years. The hypocritical know-it-alls actually did not know the true meaning of God's Law since they did not practice it with pure hearts. Jesus demanded that pure worship, not the focus of washing hands, conformed to the spirit and truth of God the Father. In other words, Jesus expects that we bring our experience of worship into conformity with what is true about God the Father, true about Jesus the Son, and to let our spirits to be authentically awakened and moved by that truth.
