14 That the blessing of Abraham might come on the Gentiles through Christ Jesus: that we may receive the promise of the Spirit by faith.
15 Brethren (I speak after the manner of man,) yet a man's testament, if it be confirmed, no man despiseth, nor addeth to it.
16 To Abraham were the promises made and to his seed. He saith not, And to his seeds, as of many: but as of one, And to thy seed, which is Christ.
17 Now this I say, that the testament which was confirmed by God, the law which was made after four hundred and thirty years, doth not disannul, to make the promise of no effect.
18 For if the inheritance be of the law, it is no more of promise. But God gave it to Abraham by promise.
19 Why then was the law? It was set because of transgressions, until the seed should come, to whom he made the promise, being ordained by angels in the hand of a mediator.
20 Now a mediator is not of one: but God is one.
