Charles Ellicott Commentary 1 Kings 17:3

"Get thee hence, and turn thee eastward, and hide thyself by the brook Cherith, that is before the Jordan." — 1 Kings 17:3 (ASV)

The brook Cherith —properly “the torrent (or valley) Cherith, facing the Jordan”; evidently one of the ravines running into the Jordan valley, probably on the east from the prophet’s own land of Gilead.
