Targum sa Genesis 34:31: Targum Jonathan & Targum Jerusalem

And Shimeon and Levi answered, It would not have been fit to be said in the congregations of Israel that the uncircumcised polluted the virgin, and the worshippers of idols debased the daughter of Jakob: but it is fit that it should be said, The uncircumcised were slain on account of the virgin, and the worshippers of idols on account of the daughter of Jakob. Shekem bar Hamor will not (now) deride us with his words; for as a whorish woman and an outcast who hath no avenger would he have made our sister, if we had not done this thing.

The two sons of Jakob answered together, and said to Israel their father, It would not be fit to be said in the congregations of Israel, in their house of instruction, that the uncircumcised polluted the virgin, and the worshippers of idols the daughter of Jakob; but it is fit that it be said in the congregations of Israel and in their house of instruction, that the uncircumcised were put to death for the sake of the virgin, and the worshippers of idols because they had defiled Dinah the daughter of Jakob. And Shekem bar Hamor will not boast in his heart and say, As a woman who hath no man to avenge her injury, so hath Dinah the daughter of Jakob been made. And they said, As an impure woman and an outcast would he have accounted our sister.
