Vayikra 22:1-2

Orthodox Jewish Bible

22 And Hashem spoke unto Moshe, saying,

² Speak unto Aharon and to his Banim, that they separate themselves from the kodashim of the Bnei Yisroel which they set apart as kodesh unto Me, so that they will not commit Chillul ha-shem of Shem Kodshi: I am Hashem.
