Your fathers went down to Egypt, seventy in all, and now the LORD your God has made you as numerous as the stars in the sky.
Here is a most pathetic exhortation to obedience, inferred from the premises, and urged with very powerful arguments and a great deal of persuasive rhetoric. Moses brings it in like an orator, with an appeal to his auditors And now, Israel, what doth the Lord thy God require of thee? Deu 10:12. Ask what he requires; as David (Psa 116:12), What shall I render?
Commenting on Deuteronomy 10:12-22
Thy fathers went down into Egypt with seventy persons,.... That is, in all; for there were not seventy besides Jacob and the patriarchs his sons, but with them; see Gen 46:26 and now the Lord thy God hath made thee as the stars of heaven for multitude; as he promised they should be, Gen 15:5. Next: Deuteronomy Chapter 11
Deu 10:22 One marvel among these great and terrible acts of the Lord as to be seen in Israel itself, which had gone down to Egypt in the persons of its fathers as a family consisting of seventy souls, and now, notwithstanding the oppression it suffered there, had grown into an innumerable nation. So marvellously had the Lord fulfilled His promise in Gen 15:5.
