Excerpts from Matthew Henry's Commentary on First Kings 19:9-14
The visit God paid to [Elijah] there and the enquiry he made concerning him: The word of the Lord came to him. We cannot go any where to be out of the reach of God's eye, his arm, and his word. Whither can I flee from thy Spirit? Ps. 139:7, &c. God will take care of his out-casts; and those who, for his sake, are driven out from among men, he will find, and own, and gather with everlasting loving-kindnesses. John saw the visions of the Almighty when he was in banishment in the isle of Patmos, Rev. 1:9.
The question God puts to the prophet it, What doest thou here, Elijah? 5:9, and again 5:13. This is a reproof:
For his fleeing hither. "What brings thee so far from home? Dost thou flee from Jezebel? Couldst thou not depend upon almighty power for thy protection?" Lay the emphasis upon the pronoun thou. "What thou! So great a man, so great a prophet, so famed for resolution—dost thou flee thy country, forsake thy colors thus?" This cowardice would have been more excusable in another, and not so bad an example. Should such a man as I flee? Neh. 6:11. Howl, fir-trees, if the cedars be thus shaken.
For his fixing here. "What doest thou here, in this cave? Is this a place for a prophet of the Lord to lodge in? Is this a time for such men to retreat, when the public has such need of them?" In the retirement to which God sent Elijah (ch. 17.) he was a blessing to a poor widow at Sarepta, but here he had no opportunity of doing good. Note, It concerns us often to enquire whether we be in our place and in the way of our duty. "Am I where I should be, whither God calls me, where my business lies, and where I may be useful?"
The account [Elijah] gives of himself, in answer to the question put to him (v. 10), and repeated, in answer to the same question, v. 14.
He excuses his retreat, and desires it may not be imputed to his want of zeal for reformation, but to his despair of success. For God knew, and his own conscience witnessed for him, that as long as there was any hope of doing good he had been very jealous for the Lord God of Hosts; but now that he had laboured in vain, and all his endeavors were to no purpose, he thought it was time to give up the cause, and mourn for what he could not mend. Abi in cellam, et dic, Miserere mei—"Away to thy cell, and cry, Have compassion on me."
He complains of the people, their obstinacy in sin, and the height of impiety to which they had arrived: "The children of Israel have forsaken thy covenant, and that is the reason I have forsaken them; who can stay among them, to see every thing that is sacred ruined and run down?" This the apostle calls his making intercession against Israel, Rom. 11:2, 3. He had often been, of choice, their advocate, but now he is necessitated to be their accuser, before God. Thus John 5:45, There is one that accuseth you, even Moses, whom you trust. Those are truly miserable that have the testimony and prayers of God's prophets against them. He charges them with having forsaken God's covenant; though they retained circumcision, that sign and seal of it, yet they had quitted his worship and service, which was the intention of it. Those who neglect God's ordinances, and let fall their communion with him, do really forsake his covenant, and break their league with him.
At last he perceived a still small voice, in which the Lord was, that is, by which he spoke to him, and not out of the wind, or the earthquake, or the fire. Those struck an awe upon him, awakened his attention, and inspired humility and reverence; but God chose to make known his mind to him in whispers soft, not in those dreadful sounds. When he perceived this,
He wrapped his face in his mantle, as one afraid to look upon the glory of God, and apprehensive that it would dazzle his eyes and overcome him. The angels cover their faces before God in token of reverence, Isa. 6:2. Elijah hid his face in token of shame for having been such a coward as to flee from his duty when he had such a God of power to stand by him in it. The wind, and earthquake, and fire, did not make him cover his face, but the still voice did. Gracious souls are more affected by the tender mercies of the Lord than by his terrors.
He stood at the entrance of the cave, ready to hear what God had to say to him. This method of God's manifesting himself here at Mount Horeb seems to refer to the discoveries God formerly made of himself at this place to Moses.
[1.] Then there was a tempest, an earthquake, and fire (Heb. 12:18); but, when God would show Moses his glory, he proclaimed his goodness; and so here: He was, the Word was, in the still small voice.
[2.] Then the law was thus given to Israel, with the appearances of terror first and then with a voice of words; and Elijah being now called to revive that law, especially the first two commandments of it, is here taught how to manage it; he must not only awaken and terrify the people with amazing signs, like the earthquake and fire, but he must endeavour, with a still small voice, to convince and persuade them, and not forsake them when he should be addressing them. Faith comes by hearing the word of God; miracles do but make way for it.
[3.] Then God spoke to his people with terror; but in the gospel of Christ, which was to be introduced by the spirit and power of Elijah, he would speak by a still small voice, the dread of which should not make us afraid; see Heb. 12:18, &c.
The comfortable information God gives him of the number of Israelites who retained their integrity, though he thought he was left alone (v. 18): I have left 7000 in Israel (besides Judea) who have not bowed the knee to Baal. Note:
In times of the greatest degeneracy and apostasy God has always had, and will have, a remnant faithful to him, some that keep their integrity and do not go down the stream. The apostle mentions this answer of God to Elijah (Rom. 11:4) and applies it to his own day, when the Jews generally rejected the gospel. Yet, says he, at this time also there is a remnant, v. 5.
It is God's work to preserve that remnant, and distinguish them from the rest, for without his grace they could not have distinguished themselves: I have left me; it is therefore said to be a remnant according to the election of grace.
It is but a little remnant, in comparison with the degenerate race; what are 7000 to the thousands of Israel? Yet, when those of every age come together, they will be found many more, 12,000 sealed out of each tribe, Rev. 7:4.
God's faithful ones are often his hidden ones (Ps. lxxxiii. 3), and the visible church is scarcely visible, the wheat lost in the chaff and the gold in the dross, till the sifting, refining, separating day comes.
The Lord knows those that are his, though we do not; he sees in secret.
There are more good people in the world than some wise and holy men think there are. Their jealousy of themselves, and for God, makes them think the corruption is universal; but God sees not as they do. When we come to heaven, as we shall miss a great many whom we thought to meet there, so we shall meet a great many whom we little thought to find there. God's love often proves larger than man's charity and more extensive.
