Galatians 3:15-17 Darby Translation (DARBY)
15 Brethren, (I speak according to man,) even man's confirmed covenant no one sets aside, or adds other dispositions to.
16 But to Abraham were the promises addressed, and to his seed: he does not say, And to seeds, as of many; but as of one, And to thy seed; which is Christ.
17 Now I say this, A covenant confirmed beforehand by God, the law, which took place four hundred and thirty years after, does not annul, so as to make the promise of no effect.
Galatians 3:15-17 New International Version (NIV)
The Law and the Promise
15 Brothers and sisters, let me take an example from everyday life. Just as no one can set aside or add to a human covenant that has been duly established, so it is in this case. 16 The promises were spoken to Abraham and to his seed. Scripture does not say “and to seeds,” meaning many people, but “and to your seed,”[a] meaning one person, who is Christ. 17 What I mean is this: The law, introduced 430 years later, does not set aside the covenant previously established by God and thus do away with the promise.
