Adam Clarke's Bible Commentary Verse 5. As he lay and slept] Excessive anguish of mind frequently induces sleep, as well as great fatigue of body.
An angel touched him] He needed refreshment, and God sent an angel to bring him what was necessary.
Matthew Henry Commentary
Verses 1-8 - Jezebel sent Elijah a threatening message. Carnal hearts are hardene and enraged against God, by that which should convince and conque them. Great faith is not always alike strong. He might be serviceabl to Israel at this time, and had all reason to depend upon God' 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 an strong, it was in the Lord, and the power of his might; but of himsel 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 car that we are furnished with grace sufficient.
