1 Kings 18:28

And they cried aloud
Trying to make him hear, if possible: and cut themselves after their manner with knives and lancets, till the
blood gushed out upon them;
so the priests of Heathen deities used to slash themselves on their shoulders, arms, and thighs, in their devotions to them, as many writers observe ^F26, fancying their gods were delighted with human blood; particularly the priests of Bellona {a}, and the worshippers of the Syrian goddess ^F2, and of the Egyptian Isis ^F3.
