Genesis 34:24

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. The expression is repeated in order to show that there was no exception among all the men of Shechem. They accepted the rite all the more readily, since it was by no means unknown among Oriental nations. Thus the people of Shechem, heathen though they were, acted in good faith, just as the outward honesty of many an unbeliever in our days puts to shame those that confess the true God.
