Leviticus 24:5-9

“You must bake twelve flat loaves of bread from choice flour, using four quarts of flour for each loaf. Place the bread before the LORD on the pure gold table, and arrange the loaves in two stacks, with six loaves in each stack. Put some pure frankincense near each stack to serve as a representative offering, a special gift presented to the LORD. Every Sabbath day this bread must be laid out before the LORD as a gift from the Israelites; it is an ongoing expression of the eternal covenant. The loaves of bread will belong to Aaron and his descendants, who must eat them in a sacred place, for they are most holy. It is the permanent right of the priests to claim this portion of the special gifts presented to the LORD.”
