IV. The extent of this answer which God had given them—to all the house of Israel, v. 7, 8. The same thing is repeated, which intimates God's just displeasure against hypocrites, who mock him with the shows and forms of devotion, while their hearts are estranged from him and at war with him. Observe, 1. To whom this declaration belongs. It concerns not only every one of the house of Israel (as before, v. 4), but the stranger that sojourns in Israel; let him not think it will be an excuse for him in his idolatries that he is but a stranger and a sojourner in Israel, and does but worship the gods that his father served and that he himself was bred up in the service of; no, let him not expect any benefit from Israel's oracles or prophets unless he thoroughly renounce his idolatry. Note, Even proselytes shall not be countenanced if they be not sincere: a dissembled conversion is no conversion. 2. The description here given of hypocrites: They separate themselves from God by their fellowship with idols; they cut themselves off from their relation to God and their interest in him; they break off their acquaintance and intercourse with him, and set themselves at a distance from him. Note, Those that join themselves to idols separate themselves from God; nor shall any be for ever separated from the vision and fruition of God, but such as now separate themselves from his service and wilfully withdraw their allegiance from him. But there are those who thus separate themselves from God, and yet come to the prophets with a seeming respect and deference to their office, to enquire of them concerning God, in order to satisfy a vain curiosity, to stop the mouth of a clamorous conscience, or to get or save a reputation among men, but without any desire to be acquainted with God or any design to be ruled by him. 3. The doom of those who thus trifle with God and think to impose upon him: "I the Lord will answer him by myself; let me alone to deal with him; I will give him an answer that shall fill him with confusion, that shall make him repent of his daring impiety." He shall have his answer, not by the words of the prophet, but by the judgments of God. And I will set my face against that man, which denotes great displeasure against him and a fixed resolution to ruin him. God can outface the most impenitent sinner. The hypocrite thought to save his credit, nay, and to gain applause, but, on the contrary, God will make him a sign and a proverb, will inflict such judgments upon him as shall make him remarkable and contemptible in the eyes of all about him; his misery shall be made use of to express the greatest misery, as when the worst of sinners are said to have their portion appointed them with hypocrites, Matt. xxiv. 51. God will make him an example; his judgments upon him shall be for warning to others to take heed of mocking God: for thus shall it be done to the man that separates himself from God, and yet pretends to enquire concerning him. The hypocrite thought to pass for one of God's people, and to crowd into heaven among them; but God will cut him off from the midst of his people, will discover him, and pluck him out from the thickest of them; and by this, says God, you shall know that I am the Lord. By the discovery of hypocrites it appears that God is omniscient: ministers know not how people stand affected when they come to hear the word, but God does. And by the punishment of hypocrites it appears that he is a jealous God, and one that cannot and will not be imposed upon.
