He let you hear his voice from heaven so that he could instruct you; and here on earth he let you see his holy fire, and he spoke to you from it.

At Mount Sinai you came down from heaven; you spoke to your people and gave them good laws and sound teachings.

Be careful, then, and do not refuse to hear him who speaks. Those who refused to hear the one who gave the divine message on earth did not escape. How much less shall we escape, then, if we turn away from the one who speaks from heaven!

His voice shook the earth at that time, but now he has promised, "I will once more shake not only the earth but heaven as well."
