A commandment is an order like "You shall not murder." It is an action that you could take, but are being ordered not to take. How would someone violate the Jewish 1st commandment?
If it were something like "I am the Lord Your God, who brought you out of the land of Egypt, out of the house of bondage, and you shall never suggest that that isn't what happened", then it would be a commandment. As it stands, it's not a commandment, it's just backstory.
