12 Tamid 29b (top) - Continuing cases where we find exaggerations in Torah, Neviim, words of Chachamim - Opinion of R' Yanai bar Nachmani in the name of Shmuel that only the cases of Tapuach, Gefen, and Paroches were exaggerations. The Tamid did indeed drink from a golden cup - "Ein aniyus b'mako ashirus" - Incredible size of the Golden Grape Vine adorning the entrance to the Bais Hamikdash - Incredible size of the Paroches - Reason that olive wood and grape-vine wood cannot be used for the wood on the Mibei'ach (Either due to its knots which cause excessive smoke, or yishuv Eretz Yisroel)
