'Works of the Law' in the Bible

but knowing that a man is not accepted as righteous by the works of the Law, but by faith in Christ Jesus, we also have believed in Christ Jesus, that we might be accepted as righteous by faith in Christ, and not by the works of the Law; for by the works of the Law shall no flesh be accepted as righteous.

This only I desire to learn from you: Was it from the works of the Law that ye received the Spirit, or by the preaching of faith?

Doth he then who is supplying to you the Spirit, and working miracles among you, do it by the works of the Law, or by the preaching of faith?

For as many as rely on the works of the Law are under a curse; for it is written, "Cursed is every one that continueth not in all things which are written in the book of the Law, to do them."
