Leviticus 24:2-4

BSB(i) 2 “Command the Israelites to bring you pure oil of pressed olives for the light, to keep the lamps burning continually. 3 Outside the veil of the Testimony in the Tent of Meeting, Aaron is to tend the lamps continually before the LORD from evening until morning. This is to be a permanent statute for the generations to come. 4 He shall tend the lamps on the pure gold lampstand before the LORD continually.
