Genesis 11:5-7

Now the LORD came down to see the city and the tower which the sons of men had built. And the LORD said, “Behold, they are one [unified] people, and they all have the same language. This is only the beginning of what they will do [in rebellion against Me], and now no evil thing they imagine they can do will be impossible for them. Come, let Us (Father, Son, Holy Spirit) go down and there confuse and mix up their language, so that they will not understand one another’s speech.”
