There’s also only one set of laws the Bible itself says are called the ten commandments and it’s not either of those. In fact, it’s the laws Moses wrote after getting pissed off at the idolaters and decided the first set weren’t explicit enough about what his god did not want people to doing.
To make it clear: no yeast in blood sacrifices and don’t boil a baby goat in its mothers milk. Or else.
(Note that the Old Testament doesn’t really make it clear what the ‘or else’ is going to be in your own case, just that God is a big mean motherfucker and you don’t want to get on his bad side.)
