3:19 {22} Wherefore then [serveth] the law? It was added because of {o} transgressions, {p} till the seed should come to whom the promise was made; {23} [and it was] {q} ordained by {r} angels in the hand of a mediator.
(22) An objection which rises from the former answer: if the inheritance is not by the Law (in the least way) then why was the Law given after the promise was made? In order, the apostle says, to reprove men of sin, and so to teach them to look to Christ, in whom at length that promise of saving all people together should be fulfilled; the Law was not given in order to justify men.
(o) That men might understand by discovering their sins that they are only saved by the grace of God, which he revealed to Abraham, and that in Christ.
(p) Until the partition wall was broken down, and that full seed sprang up, made of two peoples, both of Jews and Gentiles. For by this word seed we may not understand Christ alone by himself, but coupled and joined together with his body.
(23) A confirmation of the former answer taken from the manner and form of giving the Law: for it was given by angels, striking a great terror into all, and by Moses a mediator coming between. Now they that are one need no mediator, but they that are in any way separated, and that are at variance one with another, do. Therefore the Law itself and the mediator were witnesses of the wrath of God, and not that God would by this means reconcile men to himself and abolish the promise, or add the Law to the promise.
(q) Commanded and given, or proclaimed.
(r) By the service and ministry.
3:19 Wherefore then [serveth] the law? What was its object then?
It was added because of transgressions. Added in order to restrain transgressions among men, and especially among the fleshly race of Abraham, until the promised seed,
to whom the promise was made, even Christ, should come. It was therefore only to last until that seed came.
Ordained by angels in the hand of a mediator. Communicated through the means of angels to the mediator between Israel and God; that is, to Moses. See Ac 7:53 Heb 2:2 De 33:2 De 5:5.
3:19 It - The ceremonial law. Was added - To the promise. Because of transgressions - Probably, the yoke of the ceremonial law was inflicted as a punishment for the national sin of idolatry, Exod 32:1, at least the more grievous parts of it; and the whole of it was a prophetic type of Christ. The moral law was added to the promise to discover and restrain transgressions, to convince men of their guilt, and need of the promise, and give some check to sin. And this law passeth not away; but the ceremonial law was only introduced till Christ, the seed to or through whom the promise was made, should come. And it was ordained by angels in the hand of a mediator - It was not given to Israel, like the promise to Abraham, immediately from God himself; but was conveyed by the ministry of angels to Moses, and delivered into his hand as a mediator between God and them, to remind them of the great Mediator.
3:19-22 If that promise was enough for salvation, wherefore then serveth the law? The Israelites, though chosen to be God's peculiar people, were sinners as well as others. The law was not intended to discover a way of justification, different from that made known by the promise, but to lead men to see their need of the promise, by showing the sinfulness of sin, and to point to Christ, through whom alone they could be pardoned and justified. The promise was given by God himself; the law was given by the ministry of angels, and the hand of a mediator, even Moses. Hence the law could not be designed to set aside the promise. A mediator, as the very term signifies, is a friend that comes between two parties, and is not to act merely with and for one of them. The great design of the law was, that the promise by faith of Jesus Christ, might be given to those that believe; that, being convinced of their guilt, and the insufficiency of the law to effect a righteousness for them, they might be persuaded to believe on Christ, and so obtain the benefit of the promise. And it is not possible that the holy, just, and good law of God, the standard of duty to all, should be contrary to the gospel of Christ. It tends every way to promote it.
