Bereshis 11:4-6

Orthodox Jewish Bible

⁴ And they said, Come, let us build us an Ir and a Migdal, whose rosh (top) may reach unto Shomayim; and let us make us a shem, otherwise we shall be scattered abroad upon the face of kol HaAretz.

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.
