A blood ritual of some kind is my best guess. They say they are of the law.. so...<br />(Lev 17:14)  For the life of every creature is its blood: its blood is its life. Therefore I have said to the people of Israel, You shall not eat the blood of any creature, for the life of every creature is its blood. Whoever eats it shall be cut off.<br />My question is this the blood of man or animal? Children? The only thing that makes sense is they are in defiance of God Almighty. In rebellion, so they defile themselves in these mockery rituals.
