24 All who went out of the gate of his city listened to Hamor, and to Shechem his son; and every male was circumcised, all who went out of the gate of his city.
25 On the third day, when they were sore, two of Jacob’s sons, Simeon and Levi, Dinah’s brothers, each took his sword, came upon the unsuspecting city, and killed all the males.
26 They killed Hamor and Shechem, his son, with the edge of the sword, and took Dinah out of Shechem’s house, and went away.
