Charles Spurgeon Commentary 1 Kings 17:5

"So he went and did according unto the word of Jehovah; for he went and dwelt by the brook Cherith, that is before the Jordan." — 1 Kings 17:5 (ASV)

So he went and did according unto the word of the LORD: for he went and dwelt by the brook Cherith, that is before Jordan.

It is the glory of Elijah that he does whatever God bids him, asking no questions. He simply, like a child, goes to the brook just as, like a hero, he had previously stood before the king.
