Genesis 34:23

20 And Hamor and Shechem his son came to the gate of their city, and communed with the men of their city, saying,

21 These men [are] peaceable with us, therefore let them dwell in the land, and trade therein: for the land, behold, [it is] large enough for them: let us take their daughters to us for wives, and let us give them our daughters.

22 Only herein, will the men consent to us to dwell with us, to be one people, if every male among us shall be circumcised, as they [are] circumcised.

23 [Will] not their cattle, and their substance, and every beast of theirs [be] ours? only let us consent to them, and they will dwell with us.

24 And to Hamor and to 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.

25 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 boldly, and slew all the males.

26 And they slew Hamor and Shechem his son with the edge of the sword, and took Dinah out of Shechem's house, and went out.
