Galatians 3:17-19

17What I am saying is this: the Law, which came 1430 years later, does not invalidate a covenant previously ratified by God, so as to nullify the promise. 18For 2if the inheritance is 3based on law, it is no longer 4based on a promise; but 5God has granted it to Abraham by means of a promise.

196Why the Law then? It was added on account of the 7violations, having been 8ordered through angels 9at the hand of a 10mediator, until 11the Seed would come to whom the promise had been made.
