《Genesis》4:8
And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.
《Matthew》23:35
That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias, whom ye slew between the temple and the altar.
Explain:
Here Jesus hinted that the ancestor of Jewish killed Abel. so the blood of righteous Abel was upon Jewish. Oberviously Cain was the ancestor of Jewish.
