Shemot 32:25-27

Orthodox Jewish Bible

²⁵ And when Moshe saw that HaAm were exposed; (for Aharon had exposed them to derision among their enemies;)

²⁶ Then Moshe stood in the sha’ar of the machaneh, and said, Who is on Hashem’s side? Let him rally unto me. And all the Bnei Levi gathered themselves together unto him.

²⁷ And he said unto them, Thus saith Hashem Elohei Yisroel, Put every man his cherev by his side, and go in and out from sha’ar to sha’ar throughout the machaneh, and slay every man his brother, and every man his companion, and every man his neighbor.
