Vayikra 24:1-3

Orthodox Jewish Bible

24 And Hashem spoke unto Moshe, saying,

² Command the Bnei Yisroel, that they bring unto thee pure shemen zayit beaten for the light, to kindle the Ner Tamid (Perpetual Lamp).

³ Outside the Parochet (Curtain) of the Edut, in the Ohel Mo’ed shall Aharon set it in order from erev unto boker before Hashem tamid (continually); it shall be a chukkat olam in your dorot.
