Leviticus 24:2-9

2“Command the Israelites to bring you clear oil of pressed olives for the light so that the lamps may be kept burning continually. 3Outside the curtain that shields the ark of the covenant law in the tent of meeting, Aaron is to tend the lamps before the Lord from evening till morning, continually. This is to be a lasting ordinance for the generations to come. 4The lamps on the pure gold lampstand before the Lord must be tended continually. 5“Take the finest flour and bake twelve loaves of bread, using two-tenths of an ephah for each loaf. 6Arrange them in two stacks, six in each stack, on the table of pure gold before the Lord. 7By each stack put some pure incense as a memorial portion to represent the bread and to be a food offering presented to the Lord. 8This bread is to be set out before the Lord regularly, Sabbath after Sabbath, on behalf of the Israelites, as a lasting covenant. 9It belongs to Aaron and his sons, who are to eat it in the sanctuary area, because it is a most holy part of their perpetual share of the food offerings presented to the Lord.”
