Jamieson, Fausset & Brown, on 1Cor 14:21

“In the law it is written: In other tongues and other lips I will speak to this people; and neither so will they hear me, saith the Lord.”

“In the law--as the whole Old Testament is called, being all of it the law of God. Compare the citation of the Psalms as the "law," Joh 10:34. Here the quotation is from Isa 28:11-12, where God virtually says of Israel, This people hear Me not, though I speak to. them in the language with which they are familiar; I will therefore speak to them in other tongues, namely, those of the foes whom I will send against them; but even then they will not hearken to Me; which Paul thus applies, Ye see that it is a penalty to be associated with men of a strange tongue, yet ye impose this on the Church [GROTIUS]; they who speak in foreign tongues are like "children" just "weaned from the milk" (Isa 28:9), "with stammering lips" speaking unintelligibly to the hearers, appearing ridiculous (Isa 28:14), or as babbling drunkards (Act 2:13), or madmen (Co1 14:23).”
