Numbers play an important role in Judaic ritual practices and are believed to be a means for understanding the divine. A Mishnaic textual source, Pirkei Avot 3:23, makes clear that the use of gematria is dated to at least the Tannaic period. This marriage between the symbolic and the physical found its pinnacle in the creation of the Tabernacle. The Hebrew word for symbol is ot, which, in early Judaism, denoted not only a sign, but also a visible religious token of the relation between God and man. It is largely held by Jewish leadership that the numerical dimensions of the temple are a "microcosm of creation ... that God used to create the Olamot-Universes."
