On the western side of the ramp adjacent to the mizbeach, two tables were placed, one of marble and the other of silver. On the silver table the sacred vessels that were used for the Tamid * service were placed. On the marble table the parts of the offerings were placed before they were brought to the mizbeach. Following the Tamid service, two priests would stand on this table and blow trumpets as a sign for the Levites to begin singing. (Sources: Shkalim 10:4: Tamid 7:3).
