John Gill Commentary Leviticus 24:6

"And thou shalt set them in two rows, six on a row, upon the pure table before Jehovah." — Leviticus 24:6 (ASV)

And thou shalt set them in two rows
The twelve cakes: six on a row ;
not by the side of each other, but six upon one another: upon the pure table ;
the shewbread table, so called because overlaid with pure gold, and kept clean and bright, (Exodus 25:24) ; before the Lord ;
for this stood in the holy place, in the same place as the candlestick did, which has the same position, (Leviticus 24:4) ; of the mystical and typical sense of these cakes, (See Gill on Exodus 25:30).
