is an il word meaning “and then”, expressing something subsequent to something else. In the second sentence of the Babel text:
il Ã±atta jarÄ“Ã¾a rÅ«Ännie il Ã±atta jamÄesa japÅÃ±Ã±e sÅ« jekiÄ“n xÄ«nÄr il aÃ¾ Ã±atta Äke jamÄramma;
it acts as part of a coordinating conjunction connecting the three clauses in the sentence. So:
they made a journey from the east
they found a plain in the land Shinar
they made there their home
While they journeyed from the east, they found a plain in the land of Shinar and made there their home.
