Huh?
I don't think you can find an antecedent "basis" or "inspiration."
It's more specific, he called it the moral foundation. I think he may have used the word "basis" in the CNBC interview I heard, which was when I started seeing him for what he really is.
From the ethics commission's complaint:
12. On August 14, 2003, Chief Justice Moore stated publicly that he would not comply with the injunction issued to him by the District Court. Among other things, Chief Justice Moore said in his statement in response to the Order directing him to remove the monument:As Chief Justice of the State of Alabama, it is my duty to administer the justice system of our state, not to destroy it. I have no intention of removing the monument of the Ten Commandments and the moral foundation of our law. To do so would, in effect, result in the [be a] disestablishment of our system of Justice in this State. This I cannot and will not do!
