Leviticus 24:1-9

And Jehovah spake unto Moses, saying, Command the children of Israel, that they bring unto thee pure olive oil beaten for the light, to cause a lamp to burn continually. Without the veil of the testimony, in the tent of meeting, shall Aaron keep it in order from evening to morning before Jehovah continually: it shall be a statute for ever throughout your generations. He shall keep in order the lamps upon the pure candlestick before Jehovah continually. And thou shalt take fine flour, and bake twelve cakes thereof: two tenth parts of an ephah shall be in one cake. And thou shalt set them in two rows, six on a row, upon the pure table before Jehovah. And thou shalt put pure frankincense upon each row, that it may be to the bread for a memorial, even an offering made by fire unto Jehovah. Every sabbath day he shall set it in order before Jehovah continually; it is on the behalf of the children of Israel, an everlasting covenant. And it shall be for Aaron and his sons; and they shall eat it in a holy place: for it is most holy unto him of the offerings of Jehovah made by fire by a perpetual statute.
