Jamieson, Fausset and Brown on 2 Kings 8:7-8

7-8. Elisha came to Damascus--He was directed thither by the Spirit of God, in pursuance of the mission formerly given to his master in Horeb (1Ki 19:15), to anoint Hazael king of Syria. On the arrival of the prophet being known, Ben-hadad, who was sick, sent to inquire the issue of his disease, and, according to the practice of the heathens in consulting their soothsayers, ordered a liberal present in remuneration for the service.
