'Works of the Law' in the Bible

knowing that a man is not justified by works of the Law, but through faith in Jesus Christ; even we believed in Jesus Christ, that we might be justified by the faith in Christ, and not by works of the Law. For all flesh will not be justified by works of law.

This only I would learn from you: Did you receive the Spirit by works of the law, or by hearing of faith?

Then He supplying the Spirit to you and working powerful works in you, is it by works of the law, or by hearing of faith?

For as many as are out of works of the Law, these are under a curse; for it is written, "Cursed is everyone who does not continue in all things which are written in the Book of the Law, to do them."
