Peter Chrysologus — on Num 31:8 (SERMON 27)

“The soothsayer Balaam set up a scandal for the people of Israel when he went to meet their warriors, not with men in armor but with women arrayed in all their finery. He hoped to make the men drop their arms for debauchery, change their triumph into disgrace, bring the avengers of guilt into guilt themselves and—to put it briefly—to profane all their holiness into depravity. As a result of it all, when Moses was meting out punishment, he sentenced Balaam thus: "Kill Balaam the soothsayer, because he set up a stumbling block before the children of Israel."”
