Targoum sur La Genèse 11:8

And the Word of the Lord was revealed against the city, and with Him seventy angels, having reference to seventy nations, each having its own language, and thence the writing of its own hand: and He dispersed them from thence upon the face of all the earth into seventy languages. And one knew not what his neighbour would say: but one slew the other; and they ceased from building the city.
