St. Just: It seems as if there are some sensitive ears in this meeting that can not stand right the word "blood". Some general observations may convince them that we are not more cruel than the nature and the time is. Nature is following calm and irresistible its laws; man gets exterminatet where he gets in conflict with it. [...] The achievement of the easiest inventions and principles has cost millions of lives that stood in its way. Isn't it simple that in a time, when the walk of history is faster, more men get out of breath? We conclude fast and easy: Since all are made under equal circumstances, so all are equal, safe those differences made by nature itself; therefor anybody may have merits, but nobody must have advantages, neither a single nor a smaller or a larger class of individuals. - Every part of this in reality applied sentence has killed its men. The 14th July, the 10th August, the 31th May are its interpunctation signs. It took it four years to be realized in the world of bodies, and under normal circumstances, it would have taken hundreds of years and would have been interpuncted with generations. So is it astonishing that the stream of revolution on every bend, on every new turn spills out its dead bodies? We will have to add some conclusions to our sentence; shall some hundred dead bodies prevent us from doing them? Moses guided his people through the Red Ocean and the desert, untill the old rotten generation was wiped out, before he founded the new state. Law maker! We do not have the Red Ocean, nor the desert, but we do have the war and the guillotine. The Revolution is like the daughters of Pelias: they tear down mankind, to rejuvenante it. Mankind will rise from this blood pot like earth from the waves of the Flood, with strong limbs, as if it would be created the first time.
Büchner, Dantons Tod

Blood is not filthy, blood cleans everything.

Things shall not mix. Some are born as slaves, some are born as masters.

If a man sleeps with a woman during her period, than both shall be killed (Levitikus 20, 18).
If a woman has her period, she is unclean for seven days. Everything she touches is unclean for one day. A man that sleeps with a woman that is unclean is unclean for seven days. A woman bleeding out of her period shall be unclean for at least seven days and shall sacrifice two pigeons (Levitikus 15, 19ff).
If a woman gives birth to a son, she is unclean for seven days. If she gives birth to a daughter, she is unclean for fourteen days. She shall stay at home for thirty-three days, if it is a son, and sixty-six days, if it is a daughter (Levitikus 12, 1ff).

Bathing in the blood of the dragon makes you invulnerable. Eating the blood of the dragon makes you understand the language of birds.

The blood spilled by men cleans. The blood spilled by women uncleans.
