What two brothers in the bible slayed a city because of their sister?

Answer 1

I think this is what you are referring to: their names were Sim′e·on and Le′vi here is the account.

(Genesis 34:1-31) Now Di′nah the daughter of Le′ah, whom she had borne to Jacob, used to go out to see the daughters of the land. 2 And She′chem the son of Ha′mor the Hi′vite, a chieftain of the land, got to see her and then took her and lay down with her and violated her. 3 And his soul began clinging to Di′nah the daughter of Jacob, and he fell in love with the young woman and kept speaking persuasively to the young woman. 4 Finally She′chem said to Ha′mor his father: "Get me this young lady as a wife." 5 And Jacob heard that he had defiled Di′nah his daughter. And his sons happened to be with his herd in the field; and Jacob kept silent until they should come in. 6 Later Ha′mor, She′chem's father, went out to Jacob to speak with him. 7 And the sons of Jacob came in from the field as soon as they heard of it; and the men became hurt in their feelings and they grew very angry, because he had committed a disgraceful folly against Israel in lying down with Jacob's daughter, whereas nothing like that ought to be done. 8 And Ha′mor proceeded to speak with them, saying: "As for She′chem my son, his soul is attached to YOUR daughter. Give her, please, to him as a wife, 9 and form marriage alliances with us. YOUR daughters YOU are to give to us, and our daughters YOU are to take for yourselves. 10 And with us YOU may dwell, and the land will become available for YOU. Dwell and carry on business in it and get settled in it." 11 Then She′chem said to her father and to her brothers: "Let me find favor in YOUR eyes, and whatever YOU will say to me I shall give it. 12 Raise very high the marriage money and gift imposed upon me, and I stand willing to give according to what YOU may say to me; only give me the young woman as a wife." 13 And Jacob's sons began to answer She′chem and Ha′mor his father with deceit and to speak so because he had defiled Di′nah their sister. 14 And they went on to say to them: "We cannot possibly do such a thing, to give our sister to a man who has a foreskin, because that is a reproach to us. 15 Only on this condition can we give consent to YOU, that YOU become like us, by every male of YOURS getting circumcised. 16 Then we shall certainly give our daughters to YOU, and YOUR daughters we shall take for ourselves, and we shall certainly dwell with YOU and become one people. 17 But if YOU do not listen to us to get circumcised, then we will take our daughter and go." 18 And their words seemed good in the eyes of Ha′mor and in the eyes of She′chem, Ha′mor's son, 19and the young man did not delay to perform the condition, because he did find delight in Jacob's daughter and he was the most honorable of the whole house of his father. 20 So Ha′mor and She′chem his son went to the gate of their city and began to speak to the men of their city, saying: 21 "These men are peace-loving toward us. Hence let them dwell in the land and carry on business in it, as the land is quite wide before them. Their daughters we can take as wives for ourselves and our own daughters we can give to them. 22 Only on this condition will the men give us their consent to dwell with us so as to become one people, that every male of ours gets circumcised just the way they are circumcised. 23 Then their possessions and their wealth and all their livestock, will they not be ours? Only let us give them our consent that they may dwell with us." 24 Then all those going out by the gate of his city listened to Ha′mor and to She′chem his son, and all the males got circumcised, all those going out by the gate of his city. 25 However, it came about that on the third day, when they got to be aching, the two sons of Jacob, Sim′e·on and Le′vi, brothers of Di′nah, proceeded to take each one his sword and to go unsuspectedly to the city and to kill every male. 26 And Ha′mor and She′chem his son they killed with the edge of the sword. Then they took Di′nah from She′chem's house and went on out. 27 The other sons of Jacob attacked the fatally wounded men and went plundering the city, because they had defiled their sister. 28 Their flocks and their herds and their asses and what was in the city and what was in the field they took. 29 And all their means of maintenance and all their little children and their wives they carried off captive, so that they plundered all that was in the houses. 30 At this Jacob said to Sim′e·on and to Le′vi: "YOU have brought ostracism upon me in making me a stench to the inhabitants of the land, with the Ca′naan·ites and the Per′iz·zites; whereas I am few in number, and they will certainly gather together against me and assault me and I must be annihilated, I and my house." 31 In turn they said: "Ought anyone to treat our sister like a prostitute?" .(New World Translation)
