Leviticus 24:5-10

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.”

10Now the son of an Israelite woman, whose father was an Egyptian, went out among the Israelites, and he and a man of Israel quarreled and struggled with each other in the camp.
