And thou shalt put pure frankincense upon [each] row,.... Two cups of frankincense, in each of which was an handful of it, and which were set by each row of the cakes, as Jarchi observes:
that it may be on the bread for a memorial; or "for the bread", instead of it, for a memorial of it; that being to be eaten by the priests, and this to be burned on the altar to the Lord, as follows:
[even] an offering made by fire unto the Lord; not the bread that was after a time taken away, and eaten by the priests, but the frankincense.
