Leviticus 24:3-7

³Without the veil of the testimony, in the tent of meeting, shall Aaron order it from evening to morning before the LORD continually; it shall be a statute for ever throughout your generations.

⁴He shall order the lamps upon the pure candlestick before the LORD continually.

⁵And thou shalt take fine flour, and bake twelve cakes thereof: two tenth parts of an ephah shall be in one cake.

⁶And thou shalt set them in two rows, six in a row, upon the pure table before the LORD.

⁷And thou shalt put pure frankincense with each row, that it may be to the bread for a memorial-part, even an offering made by fire unto the LORD.
