Deuteronomy 4:11

8 And what great nation has laws and decisions so right as all this law which I put before you today?

9 Only take care, and keep watch on your soul, for fear that the things which your eyes have seen go from your memory and from your heart all the days of your life; but let the knowledge of them be given to your children and to your children's children;

10 That day when you were waiting before the Lord your God in Horeb, and the Lord said to me, Make all the people come together, so that hearing my words they may go in fear of me all the days of their life on earth and give this teaching to their children.

11 And you came near, waiting at the foot of the mountain; and flames of fire went up from the mountain to the heart of heaven, with dark clouds, and all was black as night.

12 And the voice of the Lord came to you out of the fire: the sound of his words came to your ears but you saw no form; there was nothing but a voice.

13 And he gave you his agreement with you, the ten rules which you were to keep, which he put in writing on the two stones of the law.

14 And the Lord gave me orders at that time to make clear to you these laws and decisions, so that you might do them in the land to which you are going, and which is to be your heritage.
