Leviticus 24:2-9

2“Command the children of Israel to bring to you clear oil from beaten olives for the light [of the golden lampstand], to make a lamp burn continually.

3Outside the veil of the Testimony [between the Holy Place and the Most Holy Place] in the Tent of Meeting, Aaron shall always keep the lamps burning before the Lord from evening until morning; it shall be a permanent statute throughout your generations.

4He shall keep the lamps burning on the pure gold lampstand before the Lord continually.

5“Then you shall take fine flour and bake twelve cakes (bread of the Presence, showbread) with it; two-tenths of an ephah shall be in each cake (loaf).

6You shall set the bread of the Presence (showbread) in two rows, six in a row, on the pure gold table before the Lord.

7You shall put pure frankincense [in two censers, one] beside each row, so that it may be with the bread as a memorial portion, an offering by fire to the Lord.

8Every Sabbath day Aaron shall arrange the showbread before the Lord continually; it is an everlasting covenant for the Israelites.

9The bread of the Presence shall be for Aaron and his sons, and they shall eat it in a sacred place, for it is for Aaron a most holy portion of the offerings by fire to the Lord, his portion forever.”
