1 Kings 18:46 - Joseph Benson’s Commentary on the Old and New Testaments

The hand of the Lord was on Elijah God gave him more than natural strength, whereby he was enabled to outrun Ahab's chariot for so many miles together. And he girded up his loins That his garments, which were long and loose, like those in use in that country, might not hinder him. And ran before Ahab To show how ready he was to honour and serve the king; that by this humble and self-denying carriage, it might appear, what he had done was not from envy or passion, but only from a just zeal for God's glory; that by his presence with the king and his courtiers, he might animate and oblige them to proceed in the reformation of religion; and, to demonstrate, that he was neither ashamed of, nor afraid for what he had done, but durst venture himself in the midst of his enemies. But surely, if Ahab had paid the respect to Elijah that he deserved, he would have taken him into his chariot, as the eunuch did Philip, that he might honour him before the elders of Israel, and confer with him further about the reformation of the kingdom: but his pride and ambition, and other corrupt dispositions, got the better of his conviction; and he was glad to get quit of him, as Felix of Paul, when he dismissed him, and adjourned his conference with him to a more convenient season.
