The Pharisees were constantly trying to undermine the Lord's ministry, while Jesus was on earth. They were in fact false religious leaders who preferred their own ways rather than God's. The Pharisees followed the ways of their father, the devil. They practised lies and deception like their father, the devil As a result they didn't stand for truth for there is no truth in Satan. Both the devil and the Pharisees and even many religious leaders today, lied and spoke half truths.
