Genesis 11
6 Ref 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 Ref Give help, let us go down, and mingle there their pronunciation, so that a man doth not understand the pronunciation of his companion.'
