Hebrews 12:18-21

Unlike your ancestors, you didn’t come to Mount Sinai—all that volcanic blaze and earthshaking rumble—to hear God speak. The earsplitting words and soul-shaking message terrified them and they begged him to stop. When they heard the words—“If an animal touches the Mountain, it’s as good as dead”—they were afraid to move. Even Moses was terrified.
