24 And all that went out at the gate of his city hearkened to Hamor and to Shechem his son; and every male was circumcised—all that went out at 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 his sword, and came upon the city boldly, and slew all the males. 26 And Hamor and Shechem his son they slew with the edge of the sword; and took Dinah out of Shechem's house; and went out. 27 The sons of Jacob came upon the slain, and plundered the city, because they had defiled their sister. 28 Their sheep, and their oxen, and their asses, and what [was] in the city, and what [was] in the field they took; 29 and all their goods, and all their little ones, and their wives took they captive, and plundered them, and all that was in the houses. 30 And Jacob said to Simeon and Levi, Ye have troubled me, in that ye make me odious among the inhabitants of the land—among the Canaanites and the Perizzites; and I am few men in number, and they will gather themselves against me and smite me, and I shall be destroyed, I and my house.

Commentary on Genesis 34:20-31

(Read Genesis 34:20-31)

The Shechemites submitted to the sacred rite, only to serve a turn, to please their prince, and to enrich themselves, and it was just with God to bring punishment upon them. As nothing secures us better than true religion, so nothing exposes us more than religion only pretended to. But Simeon and Levi were most unrighteous. Those who act wickedly, under the pretext of religion, are the worst enemies of the truth, and harden the hearts of many to destruction. The crimes of others form no excuse for us. Alas! how one sin leads on to another, and, like flames of fire, spread desolation in every direction! Foolish pleasures lead to seduction; seduction produces wrath; wrath thirsts for revenge; the thirst of revenge has recourse to treachery; treachery issues in murder; and murder is followed by other lawless actions. Were we to trace the history of unlawful commerce between the sexes, we should find it, more than any other sin, ending in blood.
