Thematic Bible: Lighting and trimming the lamps of the sanctuary

You shall command the Israelites to provide you with pure oil of crushed olives for the light, to cause it to burn continually [every night]. In the Tent of Meeting [of God with His people], outside the veil which sets apart the Testimony, Aaron and his sons shall keep it burning from evening to morning before the Lord. It shall be a statute to be observed on behalf of the Israelites throughout their generations.
