confound their language
11:7 confound their language. In some inexplicable manner, God altered the brain/nerve/speech apparati of the Babylonian rebels to give each family unit (possibly the seventy families of Genesis 10) its own distinctive vocabulary/phonology complex. With all this, however, they all remained truly human, unchanged in basic thought processes or moral character. Further, their distinctive languages were still sufficiently alike that they could, with time and much effort, learn to speak each other’s languages. For some time to come, however, they could no longer communicate and, therefore, they could no longer cooperate. They were thus forced to obey God’s earlier command to scatter abroad and to fill the earth with different nations and governmental units.
