Leviticus 24:7

And you shall put pure frankincense on each pile , that it may go with the bread as a memorial portion as a food offering to the Lord .

By each stack put some pure incense as a memorial portion to represent the bread and to be a food offering presented to the Lord.

And thou shalt put pure frankincense upon each row, that it may be on the bread for a memorial, even an offering made by fire unto the Lord.
