Think of that next time you get together with the coven.
The twelve-person jury in the US is an inheritance from English Common Law. A deliberative body, the purpose of which is to determine truth—truth, at least, for legal purposes—it ideally constitutes, in effect, a microcosm of the society.

Easily told. There's evidence that early Germanic-speaking societies were duodecimal—twelve-based—rather than decimal. That's why to this day we count “...eleven, twelve...” and then get to the teens.
To the Hwicce, the original Anglo-Saxon-speaking Tribe of Witches, twelve was the “long ten,” just as 120 was the “long hundred.”
