15Brethren, as a man I say [it], even of man a confirmed covenant no one doth make void or doth add to,
16and to Abraham were the promises spoken, and to his seed; He doth not say, `And to seeds,` as of many, but as of one, `And to thy seed,` which is Christ;
17and this I say, A covenant confirmed before by God to Christ, the law, that came four hundred and thirty years after, doth not set aside, to make void the promise,
18for if by law [be] the inheritance, [it is] no more by promise, but to Abraham through promise did God grant [it].
19Why, then, the law? on account of the transgressions it was added, till the seed might come to which the promise hath been made, having been set in order through messengers in the hand of a mediator --
20and the mediator is not of one, and God is one --
21the law, then, [is] against the promises of God? -- let it not be! for if a law was given that was able to make alive, truly by law there would have been the righteousness,
