1 Kings 18:4-8

for when Jezebel killed the prophets of the Lord, Obadiah took a hundred prophets and hid them by fifties in a cave, and provided them with bread and water.)

Then Ahab said to Obadiah, “Go through the land to all the springs of water and to all the river valleys; perhaps we will find grass and keep the horses and mules alive, and not have to kill some of the cattle.”

So they divided the land between them to survey it; Ahab went one way by himself, and Obadiah went another way by himself.

Now as Obadiah was on the way, behold, Elijah met him, and he recognized him and fell on his face and said, “Is it you, Elijah my master?”

And he said to him, “It is I. Go, say to your master, ‘Behold, Elijah is here.’ ”
