Deuteronomy 4:9-14

“Only pay attention and watch yourselves closely so that you do not forget the things which your eyes have seen and they do not depart from your heart all the days of your life. Make them known to your children and your grandchildren [impressing these things on their mind and penetrating their heart with these truths]— especially the day you stood before the LORD your God at Horeb (Mount Sinai), when the LORD said to me, ‘Assemble the people to Me and I will let them hear My words, so that they may learn to fear Me [with awe-filled reverence and profound respect] all the days they live on the land, and so that they may teach their children.’ You approached and stood at the foot of the mountain, and the mountain burned with fire to the [very] heart of the heavens: darkness, cloud and thick gloom. Then the LORD spoke to you from the midst of the fire; you heard the sound of the words, but you saw no form—there was only a voice. So He declared to you His covenant which He commanded you to follow, the Ten Commandments; and He wrote them on two tablets of stone. The LORD commanded me at that time to teach you the statutes and judgments, so that you might do them in the land which you are going over to possess.
