Leviticus 24:7-9

Amplified Bible, Classic Edition

⁷ You shall put pure frankincense [in a bowl or spoon] beside each row, that it may be with the bread as a memorial portion, an offering to be made by fire to the Lord.

⁸ Every Sabbath day Aaron shall set the showbread in order before the Lord continually; it is on behalf of the Israelites, an everlasting covenant.

⁹ And the bread 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 to the Lord made by fire, a perpetual due [to the high priest].
