Genesis 11:4-6

Young's Literal Translation

⁴ And they say, `Give help, let us build for ourselves a city and tower, and its head in the heavens, and make for ourselves a name, lest we be scattered over the face of all the earth.'

⁵ And Jehovah cometh down to see the city and the tower which the sons of men have builded;

⁶ and Jehovah saith, `Lo, the people [is] one, and one pronunciation [is] to them all, and this it hath dreamed of doing; and now, nothing is restrained from them of that which they have purposed to do.
