Jamieson, Fausset and Brown on 1 Kings 18:7-16

7-16. Obadiah was in the way ... Elijah met him--Deeming it imprudent to rush without previous intimation into Ahab's presence, the prophet solicited Obadiah to announce his return to Ahab. The commission, with a delicate allusion to the perils he had already encountered in securing others of God's servants, was, in very touching terms, declined, as unkind and peculiarly hazardous. But Elijah having dispelled all the apprehensions entertained about the Spirit's carrying him away, Obadiah undertook to convey the prophet's message to Ahab and solicit an interview. But Ahab, bent on revenge, or impatient for the appearance of rain, went himself to meet Elijah.
