Leviticus 24:3-7

Outside the veil of the testimony in the tent of meeting, Aaron shall keep it in order from evening to morning before the Lord continually; it shall be a permanent statute throughout your generations.

He shall keep the lamps in order on the pure gold lampstand before the Lord continually.

“Then you shall take fine flour and bake twelve cakes with it; two-tenths of an ephah shall be in each cake.

And you shall set them in two rows, six to a row, on the pure gold table before the Lord.

You shall put pure frankincense on each row so that it may be a memorial portion for the bread, an offering by fire to the Lord.
