I. The sin of this people, upon which the commission signed against them is grounded. God disowns them and dooms them to destruction, v. 10. But is there not a cause? Yes; for, 1. They have deserted the law of God (v. 11): The house of Israel and the house of Judah, though at variance with one another, yet both agreed to deal very treacherously against God. They forsook the worship of him, and therein violated their covenants with him; they revolted from him, and played the hypocrite with him. 2. They have defied the judgments of God and given the lie to his threatenings in the mouth of his prophets, v. 12, 13. They were often told that evil would certainly come upon them; they must expect some desolating judgment, sword or famine; but they were secure and said, We shall have peace, though we go on. For, (1.) They did not fear what God is. They belied him, and confronted the dictates even of natural light concerning him; for they said, "It is not he, that is, he is not such a one as we have been made to believe he is; he does not see, or not regard, or will not require it; and therefore no evil shall come upon us." Multitudes are ruined by being made to believe that God will not be so strict with them as his word says he will; nay, by this artifice Satan undid us all: You shall not surely die. So here: Neither shall we see sword nor famine. Vain hopes of impunity are the deceitful support of all impiety. (2.) They did not fear what God said. The prophets gave them fair warning, but they turned it off with a jest: "They do but talk so, because it is their trade; they are words of course, and words are but wind. It is not the word of the Lord that is in them; it is only the language of their melancholy fancy or their ill-will to their country, because they are not preferred." Note, Impenitent sinners are not willing to own any thing to be the word of God that makes against them, that tends either to part them from, or disquiet them in, their sins. They threaten the prophets: "They shall become wind, shall pass away unregarded, and thus shall it be done unto them; what they threaten against us we will inflict upon them. Do they frighten us with famine? Let them be fed with the bread of affliction." So Micaiah was, 1 Kings xxii. 27. "Do they tell us of the sword? Let them perish by the sword," ch. ii. 30. Thus their mocking and misusing God's messengers filled the measure of their iniquity.
