Genesis 11:1-9 YLT

1 And the whole earth is of one pronunciation, and of the same words,
2 and it cometh to pass, in their journeying from the east, that they find a valley in the land of Shinar, and dwell there;
3 and they say each one to his neighbour, `Give help, let us make bricks, and burn [them] thoroughly:' and the brick is to them for stone, and the bitumen hath been to them for mortar.
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.
7 Give help, let us go down, and mingle there their pronunciation, so that a man doth not understand the pronunciation of his companion.'
8 And Jehovah doth scatter them from thence over the face of all the earth, and they cease to build the city;
9 therefore hath [one] called its name Babel, for there hath Jehovah mingled the pronunciation of all the earth, and from thence hath Jehovah scattered them over the face of all the earth.
