"Etymology - After Jezebel, the wife of King Ahab in the Old Testament, who was defenestrated and killed for not worshiping the right god."

Hi Anu -
I do not think the fact that Jezebel was killed for not worshipping the right god is correct.
Jezebel got killed because of the judgement by a righteous God for murdering an innocent man and stealing the man's property.
Ahab, Jezebel's husband and the King of Israel, wanted the vineyard of a man named Naboth. Whne Naboth refused to sell it, Jezebel planned and executed a conspiracy to have Naboth murdered and annexing his property.
