Bereshis 11:5-7

Orthodox Jewish Bible

⁵ And Hashem came down to see the Ir and the Migdal, which Bnei HaAdam built.

⁶ And Hashem said, See, the Am is echad and they have all one language; and this they begin to do; and now nothing will be impossible for them, which they have proposed to do.

⁷ Come, let Us go down, and there confuse their sefat, that they may not understand one another’s language.
