John Calvin on Deuteronomy 7:25-26

25. The graven images of their gods. He again impresses upon them the object of the destruction of the nations, but he goes further than before. He had before forbidden them to worship their gods. He now commands them to consume their graven images with fire, for since the people were prone to superstition, such snares might easily have alienated them from God’s pure worship. Nor does he command them merely to melt the gold and silver so as to alter its shape, but he altogether interdicts its use, since it would be a contagious plague; for he shews how greatly God abominates idols, inasmuch as whosoever should touch the materials of which they were molten, would contract pollution and become accursed. This great severity might indeed seem to condemn the metals which were created for man’s use, as if they were impure, and as if the perfectness of natural things was liable to be corrupted by man. But in this way idolaters would contaminate the sun and moon, when falsely regarding them as objects of corrupt worship; and it must be answered that the gold and silver itself was by no means polluted by this impious abuse; but that, although free from all stain in itself, it was polluted in respect to the people. Such was the uncleanness of animals, not that they had in themselves any pollution, but because God had interdicted their being eaten. The pollution therefore which is now mentioned arises from a similar prohibition; for otherwise the ignorant people could not be restrained, and hence God would have that to be abominable which in itself was pure. Still this was a political precept, and only given temporarily to the ancient people; yet we gather from it how detestable idolatry is, which even infects the works of God themselves with its own filthiness.

Deuteronomy 25

Deuteronomy 25:17-19

17. Remember what Amalek did unto thee by the way, when ye were come forth out of Egypt;

17. Memento quid fecerit tibi Amalec in via, quando egressi estis ex Aegypto:

18. How he met thee by the way, and smote the hindmost of thee, even all that were feeble behind thee, when thou wast faint and weary; and he feared not God.

18. Quod tibi occurrerit in via, et te in cauda agminis aggressus sit, omnium debilium post to, quum esses lassus et fatigatus, et non timuerit Deum.

19. Therefore it shall be, when the LORD thy God hath given thee rest from all thine enemies round about, in the land which the LORD thy God giveth thee for an inheritance to possess it, that thou shalt blot out the remembrance of Amalek from under heaven; thou shalt not forget it.

19. Erit ergo quum dederit requiem Jehova Deus tuus tibi ab omnibus inimicis tuis per circuitum, in terra quam Jehova Deus tuus dat tibi in haereditatem ut possideas eam, delebis memoriam Amalec de sub coelo, ne obliviscaris.
