And he came thither unto a cave, and lodged there; and, behold, the word of the LORD came to him, and he said unto him, What doest thou here, Elijah? And he said, I have been very jealous for the LORD God of hosts: for the children of Israel have forsaken thy covenant, thrown down thine altars, and slain thy prophets with the sword; and I, even I only, am left; and they seek my life, to take it away.
Elijah tells God twice that he alone is left of the prophets and that his life is being hunted. The count turns out to be wrong, seven thousand others are named later, but the isolation he describes is the state he is actually living in.
