Moses
Deuteronomy 10:13ESV·traditional attribution

and to keep the commandments and statutes of the LORD, which I am commanding you today for your good?

Matthew Henry Presbyterian @wholebiblehenry

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?

John Gill Reformed Baptist @doctorgill

To keep the commandments of the Lord, and his statutes,.... Both the ten commands and all others: which I command thee this day for thy good; promises of temporal good things, introduction into the land of Canaan, possession of it, and continuance in it, being made to obedience to them.

Keil & Delitzsch Lutheran @keilanddelitzsch

Deu 10:12-13 The proof that Israel had no righteousness before God is followed on the positive side by an expansion of the main law laid down in Deu 6:4., to love God with all the heart, which is introduced by the words, “and now Israel,” sc., now that thou hast everything without desert or worthiness, purely from forgiving grace.
