'Later' in the Bible

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

Then fourteen years later, I again went up to Jerusalem with Barnabas, taking Titus with me.

And I say this: The law, which came 430 years later, does not revoke a covenant that was previously ratified by God and cancel the promise.

Why, then, the Law [what was its purpose]? It was added [after the promise to Abraham, to reveal to people their guilt] because of transgressions [that is, to make people conscious of the sinfulness of sin], and [the Law] was ordained through angels and delivered to Israel by the hand of a mediator [Moses, the mediator between God and Israel, to be in effect] until the Seed would come to whom the promise had been made.

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