Lamsa(i)
17 And this I say, that the covenant which was previously confirmed of God in Christ cannot be repudiated and the promise nullified by the law which came four hundred and thirty years later.
18 For if the inheritance is by the law, then it would not be as the fulfillment of promise: but God gave it to Abraham by promise.
19 Then what is the use of the law? It was added because of transgression, till the coming of the heir to whom the promise was made; and the law was given by angels by the hand of a mediator;
20 Now a mediator does not represent one alone, but God is one.
21 Is the law then against the promises of God? Far be it: for if a law had been given, which could have wrought salvation, righteousness would truly have come as the result of the law.
22 But the scripture has included everything under sin, that the promise by the faith of Jesus Christ might be given to those who believe.
23 But before faith came, we were guided by the law, while we were waiting for the faith which was to be revealed.
24 The law then was our pathfinder to bring us to Christ that we might be justified by faith.
