“Like troops of robbers waylay a man, a company of priests murders its way to Shekhem, for they have formulated a plot” (Hosea 6:9). Just as these robbers sit on the way, kill people, and take their wealth, so, Simeon and Levi did to Shekhem. But, like “a company of priests”? I wonder. Just as these priests join together at the threshing floor to take their portion, so Simeon and Levi did in Shekhem, as it is stated: “Murders its way to Shekhem” – it was proper for Simeon and Levi to have killed in Shekhem. “Shall [he render our sister] a harlot?” (Genesis 34:31) – they said: ‘What, will they treat us as worthless people?’ Who caused it? “Dina, daughter of Leah…went out.”
