Exodus 20:18-19
The Israelites are afraid of God's power
18 The people heard the loud thunder and they saw the bright lightning. They heard the noise of the trumpet. They saw the smoke on the mountain. They were so afraid that their bodies were shaking. They would not come near. 19 They said to Moses, ‘Speak to us yourself. We will listen to you. But do not let God speak to us. If he does, we will die.’
