Leviticus 24:7

Shalt put pure frankincense upon each row. — Better, shalt place pure frankincense by each pile. As the two piles of six cakes each measured together ten handbreadths in width, and as the length of the table was twelve handbreadths, there was a vacant space of two handbreadths left on the table for the two bowls with frankincense. The vacant place in question may, therefore, (1) have been divided between the two ends of the table, and a bowl with incense been put at each end on either side of the two piles; or (2) the disposable vacant space may have been left at one end of the table only, and the bowls put together on this end by one side of the two piles; or (3) each of the two piles of the cakes may have been put more or less closely to the other end of the table, thus leaving a vacant space between the two piles, into which the two bowls with the frankincense were placed. The last was the practice during the second Temple.

That it may be on the bread for a memorial. — Better, that it may be for the bread as a memorial, that is, that the frankincense may be offered up upon the altar, as God’s portion, instead of the bread which was given to the priests. By this means the prayers of the children of Israel will be brought into grateful remembrance before the Lord. (See Leviticus 2:2.)
