After heading into the Crusades, Berthold built a monastery and church on Mount Carmel dedicated to the prophet Elijah. There he gathered hermits living in the area together to form what became the Carmelite order.
Elijah was afraid and fled for his life, going to Beer-sheba of Judah. He left his servant there and went a day’s journey into the wilderness, until he came to a solitary broom tree and sat beneath it. He prayed for death: “Enough, LORD! Take my life, for I am no better than my ancestors.” He lay down and fell asleep under the solitary broom tree, but suddenly a messenger touched him and said, “Get up and eat!” He looked and there at his head was a hearth cake and a jug of water. After he ate and drank, he lay down again, but the angel of the LORD came back a second time, touched him, and said, “Get up and eat or the journey will be too much for you!” He got up, ate, and drank; then strengthened by that food, he walked forty days and forty nights to the mountain of God, Horeb. There he came to a cave, where he took shelter. But the word of the LORD came to him: Why are you here, Elijah? He answered: “I have been most zealous for the LORD, the God of hosts, but the Israelites have forsaken your covenant. They have destroyed your altars and murdered your prophets by the sword. I alone remain, and they seek to take my life.” Then the LORD said: Go out and stand on the mountain before the LORD; the LORD will pass by. There was a strong and violent wind rending the mountains and crushing rocks before the LORD—but the LORD was not in the wind; after the wind, an earthquake—but the LORD was not in the earthquake; after the earthquake, fire—but the LORD was not in the fire; after the fire, a light silent sound. When he heard this, Elijah hid his face in his cloak and went out and stood at the entrance of the cave.
