'Under the Law' in the Bible

But before faith came, we were kept in ward under the law, shut up unto the faith which should afterwards be revealed.

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

that he might redeem them that 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 led by the Spirit, ye are not under the law.
