ליטעראַטור פֿון בית שני אויף שמות 26:33

[43] It was this thought which prompted Moses when he wove the tabernacle, dividing its precincts into two, and set a curtain between the parts to distinguish the inner from the outer (Ex. 26:33); when too he gilded the sacred ark which holds the laws both within and without (Ex. 25:10), and gave the high priest two robes, the linen robe to be worn within, the many-coloured one with the long skirt to be worn outside (Ex. 28:4, Lev. 6:10).

But if you separate from the hundred a tenth as the sacred first offering to God who brings the fruits of the soul to their beginning,  their increase and their fulfilment, you will leave behind another perfect number, ninety, for it must needs be perfect, placed as it is in a debatable land between the first and the tenth ten, and thus serve to a separate sanctities from sanctities like the veil in the midst of the tabernacle (Ex. 26:33). by which things of the same genus are distinguished through division into their respective species.
