The answer is not a justification of the ways of God, nor a direct reproof of the prophet’s weakness and despondency, nor an explanation or application of what Elijah had seen. For the present, he is simply directed back into the path of practical duty. His mission is not yet over, there is still work for him to do. He receives special injunctions with respect to Hazael, Jehu, and Elisha; and he is comforted with a revelation well adapted to rouse him from his despondency: there are seven thousand who will sympathize with him in his trials, and who need his care and attention.
The wilderness of Damascus - Probably the district north of the prophet’s own country, between Bashan and Damascus itself, and which was known in later times as Iturea and Gaulanitis. Here the prophet might be secure from Jezebel, while he could readily communicate with both Israel and Damascus, and execute the commissions with which he was entrusted.
When thou comest, anoint - Rather, “and thou shalt go and anoint,” Elijah performed one only of the three commissions given to him. He appears to have been left free to choose the time for executing his commissions, and it would seem that he thought the proper occasion had not arisen either for the first or the second before his own translation. But he took care to communicate the divine commands to his successor, who performed them at the fitting moment (marginal references).
