In the law it is written,
With men of other tongues and other lips will I speak unto this people; and yet for all that will they not hear me,
says the Lord.

The Lord said this about those whom he knew in advance would not believe in the Savior. For to speak in other tongues and with other lips is to preach the New Testament. Commentary on Paul’s Epistles.
In the law. Viz, Isaiah 28:11. As Chrysostom remarks, the law is sometimes used to denote, not merely the Pentateuch, but also the Prophets and the whole of the Old Testament.
It is written, With men of other tongues and other lips will I speak unto this people. This is a difficult passage, and to understand it we must explain the passage in Isaiah cited by the Apostle. The prophet"s meaning in vers9,10 Isaiah , that God is wont to teach knowledge and wisdom to those who have left childish delights and an immature age, and are men with the capacity for knowledge; but these Jews, who (ver7) take delight in the pleasures of wine and in drunkenness, are like children—do not take solid food—and are consequently unfitted for doctrine and true wisdom. Filled with wine, they scoff at me and at other prophets who denounce to them punishments from heaven for their drunkenness and other sins, and they say. "Precept must be upon precept, line upon line . . . here a little and there a little."

Yet surely it is no where written in the Law, but as I said before, he calls always the whole of the Old Testament, the Law: both the prophets and the historical books. And he brings forward his testimony from Esaias the prophet, again covertly detracting from the glory of the gift, for their profit; nevertheless, even thus he states it with praise. For the expression, not even thus, has force to point out that the miracle was enough to astonish them; and if they did not believe, the fault was theirs. And wherefore did God work it, if they were not to believe? That He might in every case appear to do His part.
How that the Creator would speak with other tongues and other lips, whilst confirming indeed the gift of tongues by such a mention, he yet cannot be thought to have affirmed that the gift was that of another god by his reference to the Creator's prediction.
But such a one only who is vouchsafed this gift, for some cause which may be advantage to the salvation of the unbelievers, who are often put to shame, not with the demonstration of the world, but by the power of the signs; that is, such as are worthy of salvation: for all the ungodly are not affected by wonders; and hereof God Himself is a witness, as when He says in the law: "With other tongues will I speak to this people, and with other lips, and yet will they by no means believe."
