Albert Barnes Commentary Deuteronomy 10:12

"And now, Israel, what doth Jehovah thy God require of thee, but to fear Jehovah thy God, to walk in all his ways, and to love him, and to serve Jehovah thy God with all thy heart and with all thy soul," — Deuteronomy 10:12 (ASV)

After these emphatic warnings against self-righteousness, the principal topic is resumed from Deuteronomy 6:0, and this division of the discourse is drawn to a conclusion in the next two chapters by a series of direct and positive exhortations to a careful fulfillment of the duties prescribed in the first two of the Ten “Words.”

Deuteronomy 10:12: What does the Lord your God require... — A noteworthy demand. God has in the Mosaic law positively commanded many things. However, these relate to external observances, which, if need be, can be enforced. But love and veneration cannot be enforced, even by God himself. They must be spontaneous.

Hence, even under the law of ordinances where so much was peremptorily laid down, and omnipotence was ready to compel obedience, those sentiments, which are the spirit and life of the whole, have to be, as they here are, invited and solicited.
