Leviticus 24:5-8

“And you shall take fine flour and bake twelve cakes with it. Two-tenths of an ephah shall be in each cake. You shall set them in two rows, six in a row, on the pure gold table before the LORD. And you shall put pure frankincense on each row, that it may be on the bread for a memorial, an offering made by fire to the LORD. Every Sabbath he shall set it in order before the LORD continually, being taken from the children of Israel by an everlasting covenant.
