24 And unto Hamor, and unto Shechem his son, hearken do all those going out of the gate of his city, and every male is circumcised, all those going out of the gate of his city.

25 And it cometh to pass, on the third day, in their being pained, that two of the sons of Jacob, Simeon and Levi, Dinah's brethren, take each his sword, and come in against the city confidently, and slay every male; 26 and Hamor, and Shechem his son, they have slain by the mouth of the sword, and they take Dinah out of Shechem's house, and go out. 27 Jacob's sons have come in upon the wounded, and they spoil the city, because they had defiled their sister; 28 their flock and their herd, and their asses, and that which 'is' in the city, and that which 'is' in the field, have they taken; 29 and all their wealth, and all their infants, and their wives they have taken captive, and they spoil also all that 'is' in the house. 30 And Jacob saith unto Simeon and unto Levi, 'Ye have troubled me, by causing me to stink among the inhabitants of the land, among the Canaanite, and among the Perizzite: and I 'am' few in number, and they have been gathered against me, and have smitten me, and I have been destroyed, I and my house.'

Matthew Henry's Commentary on Genesis 34:24-30

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.
