1 Kings 19:13

When Elijah heard it, he wrapped his face in his mantle Through dread of God's presence, being sensible that he was neither worthy of nor able to endure the sight of God with open face. And went out and stood, &c. Which God had commanded him to do; and as he was going toward the mouth of the cave, he was affrighted and stopped in his course by the dreadful wind, and earthquake, and fire; when these were past, he proceeds, and goes on to the month of the cave. Moses was put into the cave when God's glory passed before him, but Elijah was called out of it: but neither Moses nor Elijah saw any manner of similitude. And, behold, a voice What dost thou here, Elijah? What God before spake by an angel, he now speaks to him himself immediately.
