Ezek 42:7

“"And there was an outer courtyard by the treasury, which was in the way of the outer court before the treasury: the length of it was fifty cubits. Because the length of the treasuries of the outer court was fifty cubits and the length before the face of the temple was one hundred cubits." After this it is said: And the outer court was surrounded by a wall, with treasuries along the outside walls. The length of this outer court was fifty cubits, because the length of the treasuries of the outer court was fifty cubits, and the length before the front of the temple was one hundred cubits. The surrounding wall, called the peribolus, enclosed the treasuries along the outside walls of the outer court, and it was fifty cubits in length, as we have frequently mentioned. Moreover, the length in front of the face of the temple was not fifty cubits, as it was before the treasury, but one hundred cubits: so that after the remission of all sins, we may await perfect rewards in the number one hundred (Lev. XII). Regarding the barrier, or wall, which in Hebrew is called Gader (), the Seventy have interpreted it as light, which comes from outside and illuminates the eyes of our hearts: our natural light, which operates in the senses, is not sufficient to have the perfect brightness of knowledge, unless it enters from outside through the grace of God. What first illuminates the eyes of our heart, and the outer atrium, which extends to a width of fifty cubits, makes it shine. Then, when we come before the face of the temple, we shall receive perfect rewards in the number of one hundred.”
