Galatians 3:15
King James Version
“Brethren, I speak after the manner of men; Though but a man’s covenant, yet confirmed, no man disannulleth, or addeth thereto.”
Context
12And the law is not of faith: but, The man that doeth them shall live in them.
13Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed every one that hangeth on a tree:
14That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.
15Brethren, I speak after the manner of men; Though but a man’s covenant, yet confirmed, no man disannulleth, or addeth thereto.
16Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
17And this I say, the covenant, that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect.
18For if the inheritance of the law, no more of promise: but God gave to Abraham by promise.
