'Under the Law' in the Bible

But before the faith came, we were in ward under the law, shut up together for the faith that should be revealed.

but when the fulness of time was come, God sent forth his Son born of a woman, born under the law,

that he might redeem those who were under the law, that we might receive the adoption of sons.

Tell me, ye that desire to be under the law, do ye not hear the law?

But if ye are under the conduct of the Spirit, ye are not under the law.
