Now, the people mentioned in this Scripture passage are all descendants of Noah. The Book of Genesis chapter 11 describes an event in which the descendants of Noah had built the tower of Babel. At that time, they used only one language, as it is written, “Now the whole earth had one language and one speech” (Genesis 11:1). In other words, people prior to the Babel Tower event used only one speech.
But as Noah’s descendants journeyed further and further from the east, they found a plain in the land of Shinar, which is where Iraq is now located. There they sought to avoid getting scattered abroad and to make a name for themselves by building a tower whose top would be in the heavens with bricks. And so, those descendants of Noah came to build the Tower of Babel. And so, they started building the Babel Tower, but they started building the tower using bricks that they had made instead of stones and using asphalt instead of mortar. In order to make the tower tall, they used asphalt to tower up the bricks. However, because God did not like this work, He had scattered abroad all of humankind at the time by confusing their language.
