Leviticus 24:2-4

2Command the people of Israel to bring you pure oil from beaten olives for the lamp, that a light may be kept burning regularly. 3Outside the veil of the testimony, in the tent of meeting, Aaron shall arrange it from evening to morning before the Lord regularly. It shall be a statute forever throughout your generations. 4He shall arrange the lamps on the alampstand of pure gold
Hebrew  the pure lampstand
before the Lord regularly.
