Leviticus 24:1-4

¹Then the Lord spoke to Moses, saying, ²“Command the sons of Israel that they bring to you clear oil from beaten olives for the light, to make a lamp burn continually. ³Outside the veil of testimony in the tent of meeting, Aaron shall keep it in order from evening to morning before the Lord continually; it shall be a perpetual statute throughout your generations. ⁴He shall keep the lamps in order on the pure gold lampstand before the Lord continually.
