Brethren, I speak after the manner of men; Though it is but a man's covenant, yet [if it is] confirmed, no man disannulleth or addeth to it.
Now 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.
And this I say, [that] the covenant that was confirmed before by God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of no effect.
For if the inheritance [is] by the law, [it is] no more by promise: but God gave [it] to Abraham by promise.
