11. For—rather, "Truly." This is Isaiah's reply to the scoffers: Your drunken questions shall be answered by the severe lessons from God conveyed through the Assyrians and Babylonians; the dialect of these, though Semitic, like the Hebrew, was so far different as to sound to the Jews like the speech of stammerers (compare Isa 33:19; 36:11). To them who will not understand God will speak still more unintelligibly.

     21. 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 (Ac 2:13), or madmen (1Co 14:23).
