IV. How severely God would reckon with them for this. 1. He would deprive them of the privilege of plain preaching, and speak to them with stammering lips and another tongue, v. 11. Those that will not understand what is plain and level to their capacity, but despise it as mean and trifling, are justly amused with that which is above them. Or God will send foreign armies among them, whose language they understand not, to lay their country waste. Those that will not hear the comfortable voice of God's word shall be made to hear the dreadful voice of his rod. Or these words may be taken as denoting God's gracious condescension to their capacity in his dealing with them; he lisped to them in their own language, as nurses do to their children, with stammering lips, to humor them; he changed his voice, tried first one way and then another; the apostle quotes it as a favour (1 Cor. xiv. 21), applying it to the gift of tongues, and complaining that yet for all this they would not hear. 2. He would bring utter ruin upon them. By their profane contempt of God and his word they are but hastening on their own ruin, and ripening themselves for it; it is that they may go and fall backward, may grow worse and worse, may depart further and further from God, and proceed from one sin to another, till they be quite broken, and snared, and taken, and ruined, v. 13. They have here a little and there a little of the word of God; they think it too much, and say to the seers, See not; but it proves too little to convert them, and will prove enough to condemn them. If it be not a savour of life unto life, it will be a savour of death unto death.
