Rep. Rashida Tlaib, who occupies a position at the heart of American politics, blithely retweeted an unsourced, unproven, and untrue claim that Jews living in Beit Hanina kidnapped and executed a seven-year-old boy. This is a modern version of the medieval blood libel against the Jews.
The anti-Semitic blood libel has a long history, going back to at least the 1st century A.D., when the Jewish historian Josephus rebutted a claim that Antiochus Epiphanes found a Greek man in the temple in Jerusalem being fattened for sacrifice. A thousand years later, a Byzantine document again accused Jews of kidnapping a stranger every seven years to serve as a human sacrifice in the Temple at Jerusalem.
By the 12th century, the blood libel had firmly taken in England hold after Jews were accused of ritually sacrificing William of Norwich, a young boy found stabbed in the woods. After that, until the Jews were expelled from England in 1290, Jews were routinely accused of executing children and using their blood in rituals, especially when making matzo for Passover. The Jews were then slaughtered in pogroms. The libel migrated to Europe with the same deadly consequences for Jews.
The great irony of the blood libel, of course, is that one of the central stories in the Hebrew Bible is the Binding of Isaac, in which God ends human sacrifice. The Ten Commandments, the foundation of Western morality, forbid murder. The Jewish laws governing kosher cooking even forbid using blood when cooking.
