'Later' in the Bible

Then three years later I went up to Jerusalem to become acquainted with Cephas, and stayed with him fifteen days.

What I am saying is this: the Law, which came four hundred and thirty years later, does not invalidate a covenant previously ratified by God, so as to nullify the promise.

But before faith came, we were kept in custody under the law, being shut up to the faith which was later to be revealed.
