1 Kings 18:4 - Ellicott's Commentary On The Whole Bible

Jezebel cut off the prophets. — The persecution here referred to, in which for the first time the royal power was placed in distinct antagonism to the prophetic order, is only known by this allusion. It may probably have followed on the denunciation of judgment; and Elijah’s retirement to Cherith and Zarephath may have been a means of escape from it. If Elijah’s oft-repeated phrase, “I, even I, alone remain,” is to be taken literally, Obadiah’s merciful interposition must have availed only for a time, or have simply given opportunity of escape.
