False teaching in the above! Jesus and others educated in the Law knew many Pharisees taught unauthorized additions and misinterpretations to the Law which were too burdensome. They mixed opinions with Torah, offending Jesus on many points of the Law and common sense. Keep in mind Pharisees were a relatively recently addition to the authorized scheme of authority over Israel, and their ilk didn't remain long after the Temple was destroyed in 70AD. Paul was among the last, but didn't perish with the wicked of them.
God let that destruction happen as a signal of the better covenant to come as prophesied. It ended the Levitical priesthood and all the powers attending. So now, in these last days, people read about all that and seek to revive it. Too late. The better in Christ reigns.
