Genesis 11:2-4 Young's Literal Translation (YLT)
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.'
Genesis 11:2-4 New International Version (NIV)
3 They said to each other, “Come, let’s make bricks and bake them thoroughly.” They used brick instead of stone, and tar for mortar. 4 Then they said, “Come, let us build ourselves a city, with a tower that reaches to the heavens, so that we may make a name for ourselves; otherwise we will be scattered over the face of the whole earth.”
