'Under Law' in the Bible

But before faith came, we were kept under Law, having been shut up to the faith about to be revealed.

But when the fullness of the time came, God sent forth His Son, coming into being out of a woman, having come under Law,

that He might redeem those under Law, so that we might receive the adoption of sons.

Tell me, those desiring to be under Law, do you not hear the Law?

But if you are led by the Spirit, you are not under law.
