The name of a desert war god that some monotheists in canaan became obsessed with and replaced El and the gods of their ancestors.
The monotheism and newly invented "history" became the backbone of the eternal liars known as "jews"
Later, a divine teacher would be born to these liars, refusing to use this name (not once) and rejecting their system of false worship, but they took care of that.
