Genesis 34:2, 24-25

And Shechem the son of Hamor the Hivite, the prince of the land, saw her; and he took her, and lay with her, and humbled her.

And unto Hamor and unto Shechem his son hearkened all that went out of the gate of his city; and every male was circumcised, all that went out of the gate of his city. And it came to pass on the third day, when they were sore, that two of the sons of Jacob, Simeon and Levi, Dinah’s brethren, took each man his sword, and came upon the city unawares, and slew all the males.
