Kommentar zu Wajikra 24:8

ביום השבת, ביום השבת, “Every Sabbath day;” while new breads were replacing last week’s breads, the frankincense of last week’s breads was burned up at the end of the week on the Sabbath.

יערכנו, “he shall arrange it;” the subject is the showbreads, not the branches described in Exodus 25,32. The latter were not arranged on the Sabbath but on the Sabbath eve. All the furnishings in the Tabernacle were arranged so that their length was parallel to the long walls of the structure, with the exception of the Holy Ark.
