Kabbalah zu Bereschit 11:4

Of the Giborim, (mighty ones), the third group, it is written: "The same were mighty men of old, men of renown (lit. 'men with a name')" (Beresheet 6:4). These descend from the side of those, about whom it is said: "Let us build us a city and a tower...and let us make us a name..." (Beresheet 11:4). They, this group of the mixed multitude, build synagogues and Yeshivot, putting the scroll of the Torah and a crown upon its top, not in the name of Hashem. Instead, it is done to make themselves a name, as it is written: "And let us make us a name." (The children of) the Other Side, overcame Yisrael, who are (blessed to be) like the dust of the earth. They rob them, shattering their work. Of them, it is written: "And the waters prevailed exceedingly upon the earth" (Beresheet 7:19)
