Paul and Peter both said the False Law of the Pharisees was hung on the cross.
Paul used the phrase works of the law six times and only within Romans and Galatians. Heres the full list within context:
For no human being will be justified in his sight by works of the law, since through the law comes knowledge of sin (Rom 3:20).
For we hold that a man is justified by faith apart from works of law (Rom 3:28).
Yet we know that a man is not justified by works of the law but through faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be justified by faith in Christ, and not by works of the law, because by works of the law shall no one be justified (Gal 2:16).
Let me ask you only this: Did you receive the Spirit by works of the law, or by hearing with faith? (Gal 3:2)
Does he who supplies the Spirit to you and works miracles among you do so by works of the law, or by hearing with faith? (Gal 3:5)
For all who rely on works of the law are under a curse. For it is written, Cursed be every one who does not abide by all things written in the book of the law, and do them (Gal 3:10).
Now then; if you are going to claim that these verses refer to the EXTRA stuff that Phariseeism added to the LAW; it had better be REALLY convincing.

“Works of the law” is the following of the Pharisees false law.
That was what was tripping up the Galatians, and in our time tripping up the Jewabies that call their nicolaitan “Rabbi.”
