Matt 23:1-4
Now Jesus turned to address his disciples, along with the crowd that had gathered with them. 2 "The religion scholars and Pharisees are competent teachers in God's Law. 3 You won't go wrong in following their teachings on Moses. But be careful about following them. They talk a good line, but they don't live it. They don't take it into their hearts and live it out in their behavior. It's all spit-and-polish veneer.
