John Calvin on Deuteronomy 4:39-40

39. Know therefore this day. He again inculcates what we have lately spoken of, that the glory of the one true God was proved by the miracles, but he does so by way of exhortation. For he desires them carefully and attentively to consider what God had shewn them, because in so plain a matter there would be no excuse for error or ignorance. He therefore infers from what had gone before, that the people must beware of shutting their eyes against the clear revelation of God’s power, and therefore urges them to keep it in memory, because man’s ingratitude is but too prone to forgetfulness. He afterwards reminds them wherefore God would be known, viz., that they might keep His Law and obey His statutes. The sum is, that they would be inexcusable if they did not obediently receive the Law, which they knew to have come from God; for they must needs be worse than stupid if the majesty of God, known and understood by so many proofs, did not awaken them to reverence. And lest they should undervalue the doctrine as proceeding from a mortal man, he expressly confesses, indeed, that he is the minister, and yet that he had set before them nothing which he had not received from God.

DEUTERONOMY 7

Deuteronomy 7:6-8

6. For thou art an holy people unto the Lord thy God: the Lord thy God hath chosen thee to be a special people unto himself— above all people that are upon the face of the earth.

6. Nam populus sanctus es Jehovae Deo tuo: te elegit Jehova Deus tuus— ut sis illi populus peculiaris ex omnibus populis qui sunt in superficie terrae.

7. The Lord did not set his love upon you— nor choose you— because ye were more in number than any people; (for ye were the fewest of all people;)

7. Non quia plures essetis prae omnibus populis— amavit vos Jehova— et elegit vos: (vos enim eratis pauciores omnibus populis.)

8. But because the Lord loved you— and because he would keep the oath which he had sworn unto your fathers— hath the Lord brought you out with a mighty hand— and redeemed you out of the house of bond-men— from the hand of Pharaoh king of Egypt.

8. Sed quia diligebat vos Jehova— et custodire volebat juramentum quod juraverat patribus vestris— eduxit vos Jehova in manu forti— et redemit vos e manu Pharaonis regis Aegypti.
