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).

To the wilderness of Damascus - He does not desire him to take a road by which he might be likely to meet Jezebel, or any other of his enemies.

Anoint Hazael - For what reason the Lord was about to make all these revolutions, we are told in 1 Kings 19:17. God was about to bring his judgments upon the land, and especially on the house of Ahab. This he exterminated by means of Jehu; and Jehu himself was a scourge of the Lord to the people. Hazael also grievously afflicted Israel; see the accomplishment of these purposes, 2 Kings 8 (note), and 2 Kings 9 (note).

And the Lord said unto him, go, return on thy way to the wilderness of Damascus,.... He is bid to go back the way he came, through the wilderness of Arabia, which was part of his way to Damascus, near to which was another wilderness, which took its name from thence; though Fortunatus Schacchus (x) thinks no other is meant by this phrase than returning to his former course and custom of preach the law of God, and reclaiming men from the error of their ways:

and when thou comest, anoint Hazael to be king over Syria; it is nowhere related that Elijah did go to Damascus, and anoint Hazael, though it may be he did; however he acquainted Elisha with it, and he declared it to Hazael, that he should be king of Syria, and which perhaps is all that is meant by anointing; that is, that he should be made king, and which was declared by both these prophets, see 2 Kings 8:13.

(x) Elaeochrism. Myrothec. l. 1. c. 39. col. 198.

And the LORD said unto him, Go, return on thy way to the wilderness of Damascus: and when thou comest, anoint Hazael to be king over Syria:

19:14-18 God repeated the question, What doest thou here? Then he complained of his discouragement; and whither should God's prophets go with their complaints of that kind, but to their Master? The Lord gave him an answer. He declares that the wicked house of Ahab shall be rooted out, that the people of Israel shall be punished for their sins; and he shows that Elijah was not left alone as he had supposed, and also that a helper should at once be raised up for him. Thus all his complaints are answered and provided for. God's faithful ones are often his hidden ones, Ps 83:3, and the visible church is scarcely to be seen: the wheat is lost in chaff, and the gold in dross, till the sifting, refining, separating day comes. The Lord knows them that are his, though we do not; he sees in secret. When we come to heaven we shall miss many whom we thought to have met there; we shall meet many whom we little thought to have met there. God's love often proves larger than man's charity, and far more extended.
