'Under the Law' in the Bible

My concern was because of the false brothers [those people masquerading as Christians] who had been secretly smuggled in [to the community of believers]. They had slipped in to spy on the freedom which we have in Christ Jesus, in order to bring us back into bondage [under the Law of Moses].

Now before faith came, we were kept in custody under the Law, [perpetually] imprisoned [in preparation] for the faith that was destined to be revealed,

Tell me, you who are bent on being under the Law, do you not listen to [what] the Law [really says]?
