Exodus 27:20-21 - The Lampstand Oil
20 Command the Israelites that the lighting must be provided by pure virgin olive oil so that the lamps will not go out. 21 Keep the lamps lit in the tent of meeting outside the canopy where the words of my covenant are. Aaron and his descendants must keep the lamps lit in Jehovah's presence from evening until morning. This is a long lasting law among the Israelites for generations to come.
