Exodus 27:19-21 The Voice (VOICE)
19 As for the items used in the ceremonies held in the congregation tent and the tent pegs used both inside and outside the tent, they are to be made of bronze.
20 Direct the Israelites to bring you oil from olives whipped until it is clear in order to keep the lamps burning continually and producing the best light possible. 21 From dusk till dawn—inside the tent but outside the veil shrouding the most holy place—Aaron and his sons are to keep the lamps burning in My presence. This directive stands forever and must be carried out by the priests and people of Israel throughout all generations.
