The LORD said, "Go out and stand on the mountain in the presence of the LORD, for the LORD is about to pass by." Then a great and powerful wind tore the mountains apart and shattered the rocks before the LORD, but the LORD was not in the wind. After the wind there was an earthquake, but the LORD was not in the earthquake. After the earthquake came a fire, but the LORD was not in the fire. And after the fire came a gentle whisper. When Elijah heard it, he pulled his cloak over his face and went out and stood at the mouth of the cave. Then a voice said to him, "What are you doing here, Elijah?" - 1 Kings 19:11

Also referred to as "a still, small voice" in the King James translation.
