'Under the Law' in the Bible

But before faith came, we were kept in ward under the Law, shut up unto the faith which was to be revealed.

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

to redeem those under the Law, that we might be adopted as 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.
