Neither.
Both groups of the Ten Commandments do not start that way.
First set - Exodus 20: 2-17
Second set - Exodus 34: 14-27
What is the correct saying from the ten commandments" Is it so it is written, so it shall be done?
Well, if you are talking about the 1956 movie with Yul Brynner as Rameses, his line was "So let it be written, so let it be done."
That phrase is not in the bible it is from a movie.
