There are actually 613 commandments in Deuteronomy, with the ones known as the Ten Commandments at the top of the list. Several of the 10 ? it varies depending on the translation ? are not commandments but statements, such as "I am the Lord thy God."
There's one in there about not taking the Lord's name in vain, but it isn't spelled out whether that applies to using God's name to get political power. Like a lot in the Bible, we're meant to interpret that one for ourselves.
