John Calvin on Deuteronomy 7:8

8. Because he would keep the oath. The love of God is here referred back from the children to the fathers; for he addressed the men of his own generation, when he said that they were therefore God’s treasure, because He loved them; now he adds that God had not just begun to love them for the first time, but that He had originally loved their fathers, when He chose to adopt Abraham, Isaac, and Jacob. But although he more clearly proves that the descendants of Abraham had deserved nothing of the kind, because they are God’s peculiar people only by right of inheritance, still it must be remarked that God was induced to be kind to Abraham by no other cause than mere generosity. A little further on, therefore, he will say that those who then survived were dear to God, because He had already loved their fathers. But now he still further commends the goodness of God, because He had handed down His covenant from the fathers to the children, to shew that He is faithful and true to His promises. At the end of the verse, he teaches that the deliverance of the people was both an effect and a testimony of that grace.

deuteronomy 10

Deuteronomy 10:14-17

14. Behold, the heaven, and the heaven of heavens, is the Lord’s thy God, the earth also, with all that therein is.

14. Ecce, Jehovae Dei tui sunt coeli, et coeli coelorum, terra et omnia quae in ea sunt.

15. Only the Lord had a delight in thy fathers to love them, and he chose their seed after them, even you above all people, as it is this day.

15. Tantummodo in patribus tuis beneplacitum est Jehovae, ut diligeret eos: et elegit semen eorum post eos, nempe vos, ex omnibus populis, sicut hodie.

16. Circumcise therefore the foreskin of your heart, and be no more stiff-necked.

16. Circumcidite igitur praeputium cordis vestri, et cervicem vestram ne induretis ultra.

17. For the Lord your God is God of gods, and Lord of lords, a great God, a mighty, and a terrible, which regardeth not persons, nor taketh reward.

17. Jehova enim Deus vester est, Deus deorum, et Dominus dominorum, Deus magnus, potens et terribilis.-
