Rodzaju 11:7 Midrasz: Midrash Tanchuma, Midrash Tanchuma Buber & Pirkei DeRabbi Eliezer

With the very thing (by which) the men of the tower of Babel exalted themselves He punished them. They said: Come, let us build us a city (ibid. 11:4), and through it they were punished, as it is said: Come, let us go down, and there confound their language … so the Lord scattered them (ibid., v. 8).

Come, let us go down there and confound their language (Gen. 11:7). He confounded their speech to such a degree that no one was able to understand his companion’s speech. Originally, they had spoken to each other in Hebrew, the language with which the world was created.

(Gen. 11:7) "Come, let me go down and confound."⁸⁵Again unlike the Septuagint as well as the Masoretic Text, this passage stresses the oneness of the Holy One by changing “us” to “me.”
