Charles Ellicott Commentary 1 Kings 21:17

"And the word of Jehovah came to Elijah the Tishbite, saying," — 1 Kings 21:17 (ASV)

Elijah. —We have heard nothing of him since the call of Elisha, as though he had once more retired to solitude. In the mere political service of the preceding chapter, important in the eyes of the world, he takes no part; but emerges now for the higher moral duty of rebuking crime, and avenging innocent blood, in what Eastern tyranny would deem a very trivial matter. Ahab’s address to him seems to imply wonder at his unusual appearance among men.
