Exodus 27:20-21 - The Lampstand Oil
20 Thou thyself, therefore, shalt command the sons of Israel that they bring unto thee - pure, beaten olive-oil, for giving light, - that the lamp may lift up its flame continually. 21 In the tent of meeting, outside the veil which is by the testimony, shall Aaron and his sons order it from evening until morning, before Yahweh, - a statute age-abiding, to their generations, from the sons of Israel.
