Charles Ellicott Commentary 1 Kings 20:26

"And it came to pass at the return of the year, that Ben-hadad mustered the Syrians, and went up to Aphek, to fight against Israel." — 1 Kings 20:26 (ASV)

Aphek. —The name, meaning simply a “fortress,” applies to several different places. There are two places that fit well with the Aphek of this passage and 2 Kings 13:17, as a battlefield in the plain between Israel and Syria. One is the Aphek of 1 Samuel 29:1, evidently in the plain of Esdraelon; the other is a place on the road to Damascus, about six miles east of the Sea of Galilee.
