Genesis 34:27 (KJV)

Only herein will the men consent unto us for to dwell with us, to be one people, if every male among us be circumcised, as they are circumcised.

Shall not their cattle and their substance and every beast of their's be our's? only let us consent unto them, and they will dwell with us.

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 boldly, and slew all the males.

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.

They took their sheep, and their oxen, and their asses, and that which was in the city, and that which was in the field,

And all their wealth, and all their little ones, and their wives took they captive, and spoiled even all that was in the house.

And Jacob said to Simeon and Levi, Ye have troubled me to make me to stink among the inhabitants of the land, among the Canaanites and the Perizzites: and I being few in number, they shall gather themselves together against me, and slay me; and I shall be destroyed, I and my house.

And they said, Should he deal with our sister as with an harlot?
