Genesis 11:5-7

New Revised Standard Version, Anglicised

⁵ The Lord came down to see the city and the tower, which mortals had built. ⁶ And the Lord said, ‘Look, they are one people, and they have all one language; and this is only the beginning of what they will do; nothing that they propose to do will now be impossible for them. ⁷ Come, let us go down, and confuse their language there, so that they will not understand one another’s speech.’
