>>16084756History tells of what happened.
A King of the Edomites was forced to convert to Judaism in the Kingdom of Judea, which was founded by the Judahites.
Everyone in the Kingdom of Judea, including non Judahites were referred to as Jews, like we call niggers and spics, Americans.
These Edomites became the dominant force in Judea over time, and by the time Jesus came about, majority of the Judean population were Edomites.
Edomites are the Sons of Esau.
Esau was the son of Isaac, also known as Israel, and was supposed to inherit everything from Israel.
Well Esau didn't inherit everything, rather his younger brother Jacob did, and that made Esau and his descendants extremely jealous, to the point where their jealously still lingers to this day.
