Revised Standard Version, Good News Translation, and many others begin verse 8 with So, to introduce a consequence of the LORD’s thoughts in Gen 11.7.

The LORD scattered them abroad from there: scattered is the same as in Gen 11.4. Now the LORD does to the people what they aimed to avoid. From there means from the place on the plain of Babylonia where they were living and building their city. Over the face of all the earth means “throughout the world,” “all over the earth” (Good News Translation, New English Bible). One translation renders this part of the verse as “The LORD … chased them away from that place, then they went to stay all around in every place in the world.” In some languages it is necessary to make clear how the LORD achieved his purpose; for example, “… mixed up the language of those people in order to scatter them all over.”

The consequence of being scattered is they left off building the city. The Hebrew text says only “city” and omits “and the tower,” which is added in verses 4 and 5. Some ancient versions add “and the tower” here, but it is best for translators to follow the Hebrew, as in Revised Standard Version. This clause may have to be introduced by a marker such as “therefore,” “because of that,” or “as a result.” In some languages it is necessary to say something like “Because they were scattered everywhere they could not go on building the city, and so they had to give up their work.”

Left off translates a verb meaning to stop, discontinue, give up an activity. Other ways of expressing this are, for example, “they didn’t build that town any more” and “they didn’t finish that town they were building.”
