John Calvin Commentary Deuteronomy 4:10

"the day that thou stoodest before Jehovah thy God in Horeb, when Jehovah said unto me, Assemble me the people, and I will make them hear my words, that they may learn to fear me all the days that they live upon the earth, and that they may teach their children." — Deuteronomy 4:10 (ASV)

For they were all well aware that he had undertaken nothing without the express command of God.

Finally, he proves, from the purpose and object itself of the doctrine, that God was its author, since its sole aim was that God should be purely served, and that His people might be obedient, than which nothing more just and right can be imagined.
