Albert Barnes Commentary 1 Kings 19:10

"And he said, I have been very jealous for Jehovah, the 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." — 1 Kings 19:10 (ASV)

I, even I only, am left - This is the same statement as in 1 Kings 18:22, but the meaning is different. There, Elijah merely said that he alone remained to carry out the prophet’s office, which was true; here, he implies that he is the only prophet left alive, whereas a hundred had been saved by Obadiah (1 Kings 18:4).
