According to Genesis, the confusion of languages took place in the days of Peleg. "Seder Olam" attempts to identify when exactly in Peleg's life this occurred. It concludes that the first year of Peleg's life cannot be meant (as at the time of the confusion Peleg had a younger brother, Joktan, who had several children); nor could it have occurred during the middle years of his life (for the designation "middle years" is not an exact one; had the Bible intended to indicate only a general period, it would have used the phrase "in the days of Peleg and Joktan"). The Bible must therefore mean that the confusion of languages took place in the last year of Peleg's life, which (based on the dates of the previous generations in Genesis) occurred 340 years after the Flood, or 1996 years after the creation of the world.
