Bamidbar 25:3-5

Orthodox Jewish Bible

³ And Yisroel joined himself unto Baal-Peor [see Num.23:28]; and the Af Hashem was kindled against Yisroel.

⁴ And Hashem said unto Moshe, Take Kol Rashei HaAm, and kill them, hanging them [on a tree, stake], before Hashem against the shemesh, that the fierce Af Hashem (Anger of Hashem) may be turned away from Yisroel.

⁵ And Moshe said unto the shofetim of Yisroel, Slay ye every one his men that were joined unto Baal-Peor.
