Literally 'The Generation of (the tower of) Babel
' (Ancient Hebrew).
The people of the world showed much achdut, as Genesis 11 shows, but their cause was a bit misdirected. While they worked as a tzibur, they did so to become as G-d and were therefore punished by being diseminated into the seventy nations of the world with their many tongues.
