John Calvin on Deuteronomy 27:26

26. Cursed is he that confirmeth not. Although it was God’s purpose to summon the consciences of all men before Him, and, in order that they might not only fear human judgments, He designedly threatened them with the punishment of secret sins, yet the conclusion, which is now added, extends the same judgment to all iniquities of whatever kind. Nay, He briefly declares, that whosoever shall not perform what the Law requires, are accursed. From whence Paul rightly infers, that “as many as are of the works of the Law are under the curse.” (Galatians 3:10.) For let the most perfect man come forward, and, although he may have striven ever so diligently to keep the Law, he will have at least offended in some point or other; since the declaration of James must be borne in mind, “Whosoever shall keep the whole law, and yet offend in one point, he is guilty of all;” for he that forbade murder and adultery, forbade theft also. (James 2:10, 11.) Paul indeed does not quote the very words of Moses, for he thus cites his testimony;

“Cursed is every one that continueth not in all things which are written in the book of the law to do them,” (Galatians 3:10;)

but there is no difference in the sense, since all are here condemned without exception, who have not confirmed the Law of God, so as to fulfill to the uttermost whatever it contains. Whence if is clear that, in whatever respect the deficiency betrays itself, it brings men under the curse; and to this the Israelites are commanded to assent, so as to acknowledge that they were all without exception lost, since they were involved in the curse. And now-a-days, also, it is necessary that we should all to a man be struck with the same despair, in order that, embracing the grace of Christ, we should be delivered from this melancholy state of guilt; since he was made accursed for us, that He might redeem us from the curse of the Law. (Galatians 3:13.)

Deuteronomy 11

Deuteronomy 11:26-32

26. Behold, I set before you this day a blessing and a curse;

26. Vide, ego pono coram vobis hodie benedictionem et maledictionem:

27. A blessing, if ye obey the commandments of the Lord your God, which I command you this day:

27. Benedictionem, si obedieritis praeceptis Jehovae Dei vestri, quae ego praecipio vobis hodie:

28. And a curse, if ye will not obey the commandments of the Lord your God, but turn aside out of the way which I command you this day, to go after other gods, which ye have not known.

28. Maledictionem vero, si non obedieritis praeceptis Jehovae Dei vestri, sed recesseritis e via quam ego praecipio vobis hodie, ut ambuletis post deos alienos quos non novistis.

29. And it shall come to pass, when the Lord thy God hath brought thee in unto the land whither thou goest to possess it, that thou shalt put the blessing upon mount Gerizim, and the curse upon mount Ebal.

29. Quumque introduxerit te Jehova Deus tuus in terram quam tu ingrederis ut possideas eam, tunc dabis benedictionem super montem Garizim, et maledictionem super montem Ebal.

30. Are they not on the other side Jordan, by the way where the sun goeth down, in the land of the Canaanites, which dwell in the champaign over against Gilgal, beside the plains of Moreh?

30. Annon sunt trans Jordanem post viam ad occasum solis vergentem in terra Chananaei, qui habitant in planitie e regione Gilgal, juxta campestria Moreh?

31. For ye shall pass over Jordan, to go in to possess the land which the Lord your God giveth you, and ye shall possess it, and dwell therein.

31. Vos enim transituri estis Jordanem, ut pergatis ad possidendam terram quam Jehova Deus vester dat vobis, et haereditabitis eam, et habitabitis in ea.

32. And ye shall observe to do all the statutes and judgments which I set before you this day.

32. Custodite ergo ad faciendum omnia statuta, et judicia, quae ego pono ante faciem vestram hodie.
