191 When Ahab got home, he told Jezebel everything Elijah had done, including the way he had killed all the prophets of Baal. 2 So Jezebel sent this message to Elijah: "May the gods strike me and even kill me if by this time tomorrow I have not killed you just as you killed them." 3 Elijah was afraid and fled for his life. He went to Beersheba, a town in Judah, and he left his servant there.
Matthew Henry's Commentary on 1 Kings 19:1-3
Commentary on 1 Kings 19:1-8
(Read 1 Kings 19:1-8)
Jezebel sent Elijah a threatening message. Carnal hearts are hardened and enraged against God, by that which should convince and conquer them. Great faith is not always alike strong. He might be serviceable to Israel at this time, and had all reason to depend upon God's protection, while doing God's work; yet he flees. His was not the deliberate desire of grace, as Paul's, to depart and be with Christ. God thus left Elijah to himself, to show that when he was bold and strong, it was in the Lord, and the power of his might; but of himself he was no better than his fathers. God knows what he designs us for, though we do not, what services, what trials, and he will take care that we are furnished with grace sufficient.
