Vayikra 22:1-3

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.

³ Say unto them, Whosoever he be of all your zera among your dorot, that goeth unto the kodashim, which the Bnei Yisroel treat as kodesh unto Hashem, having his tumah upon him, that nefesh shall be cut off from My presence: I am Hashem.
