John Calvin on Deuteronomy 18:14

14. For these nations. As God had just before been setting before them the punishment He was about to inflict upon these nations, in order to alarm and warn them, so now does he admonish them that the inheritance was handed over to them on this condition, that they should be mindful of so great a benefit, and beware of all pollutions; and that they succeeded the former inhabitants of the land, with a view to their being separate from them; for whence was this change, except that God might acquire to Himself a new people, and purify the land from all its defilements? Although He only mentions two classes of superstitions, yet thus, by synecdoche, He indicates them all. The sum is, that they should not be like the nations in vices and corruptions, which had been the cause of their destruction; since God had not only exterminated the men themselves, but their abominable rites also. Some divide the latter part of the verse into two clauses, “but thou shalt not do so;” and then, “Jehovah gives you the land,” which last word they supply. But I do not hesitate to think that the pronoun אתה, athah, must be thus rendered, “But as for thee;” and then I think it must be read continuously, “God hath not suffered thee to do so,” for the word נתן, nathan, is of extensive signification. The tendency of the whole is, that the prohibition of God should be of more weight with them than the example of the nations.

Deuteronomy 18:15-18

15. The Lord thy God will raise up unto thee a Prophet from the midst of thee, of thy brethren, like unto me; unto him ye shall hearken;

15. Prophetam e medio tui, ex fratribus tuis, sicut me, suscitabit tibi Jehova Deus tuns: illum audietis.

16. According to all that thou desiredst of the Lord thy God in Horeb, in the day of the assembly, saying, Let me not hear again the voice of the Lord my God, neither let me see this great fire any more, that I die not.

16. Secundum omnia quae petiisti a Jehova Deo tuo in Horeb, in die conventus, dicendo, Non adjiciam audire vocem Jehovae Dei mei, et ignem hunc magnum non videbo amplius, ne moriar.

17. And the Lord said unto me, They have well spoken that which they have spoken.

17. Et dixit Jehovah ad me, Bene egerunt in eo quod loquuti sunt.

18. I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him.

18. Prophetam suscitabo illis e medio fratrum suorum sicut to, ponamque verba mea in ore ejus: loqueturque ad eos quaecunque ei mandavero.
