SEV Biblia, Chapter 3:17
Esto pues digo: Que el Pacto previamente ratificado de Dios para con el Cristo, la ley que fue hecha cuatrocientos treinta aos despus, no lo abroga, para invalidar la promesa.
Clarke's Bible Commentary - Galatians 3:17
Verse 17. Confirmed before of God in Christ] i.e. The promise of justification, &c., made to believers in Christ Jesus, who are the spiritual seed of Christ, as they are children of Abraham, from the similitude of their faith. Abraham believed in God, and it was reckoned to him for justification; the Gentiles believed in Christ, and received justification. Probably the word Christ is to be taken, both here and in the preceding verse, for Christians, as has already been hinted. However it be taken, the sense is plainly the same; the promise of salvation must necessarily be to them who believe in Christ, for he is the promised seed, Gen. iii. 15, through whom every blessing is derived on mankind; and through his spiritual seed-the true Christians, the conquests of the cross are daily spreading over the face of the earth. The present unparalleled dispersion of the sacred writings, in all the regular languages of the universe, is a full proof that all the nations of the earth are likely to be blessed through them; but they have nothing but what they have received from and through Christ.
Four hundred and thirty years after] God made a covenant with Abraham that the Messiah should spring from his posterity. This covenant stated that justification should be obtained by faith in the Messiah. The Messiah did not come till 1911 years after the making of this covenant, and the law was given 430 years after the covenant with Abraham, therefore the law, which was given 1481 years before the promise to Abram could be fulfilled, (for so much time elapsed between the giving of the law and the advent of Christ,) could not possibly annul the Abrahamic covenant. This argument is absolute and conclusive. Let us review it. The promise to Abraham respects the Messiah, and cannot be fulfilled but in him. Christians say the Messiah is come, but the advent of him whom they acknowledge as the Messiah did not take place till 1911 years after the covenant was made, therefore no intermediate transaction can affect that covenant. But the law was an intermediate transaction, taking place 430 years after the covenant with Abraham, and could neither annul nor affect that which was not to have its fulfillment till 1481 years after. Justification by faith is promised in the Abrahamic covenant, and attributed to that alone, therefore it is not to be expected from the law, nor can its works justify any, for the law in this respect cannot annul or affect the Abrahamic covenant. But suppose ye say that the law, which was given 430 years after the covenant with Abraham, has superseded this covenant, and limited and confined its blessings to the Jews; I answer: This is impossible, for the covenant most specifically refers to the Messiah, and takes in, not the Jewish people only, but all nations; for it is written, In thy seed-the Messiah and his spiritual progeny, shall all the nations of the earth be blessed. This universal blessedness can never be confined, by any figure of speech, or by any legal act, to the Jewish people exclusively; and, as the covenant was legally made and confirmed, it cannot be annulled, it must therefore remain in reference to its object.
In opposition to us, the Jews assert that the Messiah is not yet come; then we assert, on that ground, that the promise is not yet fulfilled; for the giving of the law to one people cannot imply the fulfillment of the Abrahamic covenant, because that extends to all nations. However, therefore, the case be argued, the Jewish cause derives no benefit from it; and the conclusion still recurs, salvation cannot be attained by the works of the law, forasmuch as the covenant is of faith; and he only, as your prophets declare, who is justified by faith, shall live, or be saved.
Therefore we still conclude that those who are only under the law are under the curse; and, as it says, he that doeth these things shall live in them, and he that sinneth shall die, there is no hope of salvation for any man from the law of Moses. And the Gospel of Jesus Christ, proclaiming salvation by faith to a sinful and ruined world, is absolutely necessary, nor can it be superseded by any other institution, whether human or Divine.
How we arrive at the sum of 430 years may be seen in the note on Exod. xii. 40. Dr. Whitby also gives a satisfactory view of the matter. "The apostle refers to the promise made, Gen. xii. 3, since from that only are the 430 years to be computed, for then Abraham was 75 years old, Gen. xii. 4; from thence to the birth of Isaac, which happened when Abraham was 100 years old, (Gen. xxi. 5,) 25 years; from his birth to the birth of Jacob, 60 years, for Isaac was 60 years old when Rebecca bare him, Genesis xxv. 26. From Jacob's birth to the descent into Egypt, 130 years, as he said to Pharaoh, Gen. xlvii. 9. The abode of him and his posterity in Egypt was 215 years; so that, with their sojourning in Canaan, was 430 years;" the sum given here, and in Exodus xii. 40, where see the notes.
John Gill's Bible Commentary
Ver. 17. And this I say , etc..] Assert and affirm as a certain truth, that is not to be gainsaid; that the covenant that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul ; by the covenant is meant, not the covenant made with Adam, as the federal head of all his posterity; for this was made two thousand years before the law was given; nor that which was made with the Israelites at Mount Sinai, for that itself is the law, which was four hundred and thirty years after this covenant; nor the covenant of circumcision given to Abraham, for that was not so long by some years, before the giving of the law, as the date here fixed: but a covenant confirmed of God in Christ; a covenant in which Christ is concerned; a covenant made with him, of which he is the sum and substance, the Mediator, surety, and messenger; and such is what the Scriptures call the covenant of life and peace, and what we commonly style the covenant of grace and redemption; because the articles of redemption and reconciliation, of eternal life and salvation, by the free grace of God, are the principal things in it. This is said to be in Christ, eiv criston , with respect to Christ; though the Vulgate Latin and Ethiopic versions leave out this clause, nor is it in the Alexandrian copy, and some others; meaning either that this covenant has respect to Christ personal, he having that concern in it, as just now mentioned, and as it was made manifest and confirmed to Abraham, was promised in it to spring from him; or rather that it has respect to Christ mystical, as before, to all Abraham's spiritual seed, both Jews and Gentiles: and this is said to be confirmed of God, with respect thereunto; which must be understood, not of the first establishment of the covenant, in and with Christ, for that was done in eternity; nor of the confirmation of it by his blood, which was at his death; nor of the confirmation of it in common to the saints by the Spirit of God, who is the seal of the covenant, as he is the Spirit of promise; but of a peculiar confirmation of it to Abraham, either by a frequent repetition thereof, or by annexing an oath unto it; or rather by those rites and usages, and even wonderful appearances, recorded in ( Genesis 15:9,10) ( Genesis 15:12,13,17,18) and which was four hundred and thirty years before the law was given, which are thus computed by the learned Pareus; from the confirmation of the covenant, and taking Hagar for his wife, to the birth of Isaac,15 years; from the birth of Isaac, to the birth of Jacob,60 years, ( Genesis 25:26), from the birth of Jacob, to his going down into Egypt, 130 years, ( Genesis 47:9), from his going down to Egypt, to his death,17 years, ( Genesis 47:28) from the death of Jacob, to the death of Joseph in Egypt, 53 years, ( Genesis 50:26) from the death of Joseph, to the birth of Moses,75
