Genesis 11:7-9

Young's Literal Translation

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.
