Deuteronomy 5:19-6:3

The Lord spoke those words--those and no more--to your whole congregation at the mountain, with a mighty voice out of the fire and the dense clouds. He inscribed them on two tablets of stone, which He gave to me. When you heard the voice out of the darkness, while the mountain was ablaze with fire, you came up to me, all your tribal heads and elders, and said, "The Lord our God has just shown us His majestic Presence, and we have heard His voice out of the fire; we have seen this day that man may live though God has spoken to him. Let us not die, then, for this fearsome fire will consume us; if we hear the voice of the Lord our God any longer, we shall die. For what mortal ever heard the voice of the living God speak out of the fire, as we did, and lived? You go closer and hear all that the Lord our God says, and then you tell us everything that the Lord our God tells you, and we will willingly do it." The Lord heard the plea that you made to me, and the Lord said to me, "I have heard the plea that this people made to you; they did well to speak thus. May they always be of such mind, to revere Me and follow all My commandments, that it may go well with them and with their children forever! Go, say to them, 'Return to your tents.' But you remain here with Me, and I will give you the whole Instruction--the laws and the rules--that you shall impart to them, for them to observe in the land that I am giving them to possess." Be careful, then, to do as the Lord your God has commanded you. Do not turn aside to the right or to the left: follow only the path that the Lord your God has enjoined upon you, so that you may thrive and that it may go well with you, and that you may long endure in the land you are to possess. And this is the Instruction--the laws and the rules--that the Lord your God has commanded [me] to impart to you, to be observed in the land that you are about to cross into and occupy, so that you, your children, and your children's children may revere the Lord your God and follow, as long as you live, all His laws and commandments that I enjoin upon you, to the end that you may long endure. Obey, O Israel, willingly and faithfully, that it may go well with you and that you may increase greatly [in] a land flowing with milk and honey, as the Lord, the God of your fathers, spoke to you.
