以西結書 41:5 註釋：Rashi

and the width of the cell [Heb. הַצֵלָע,] apendiz in Old French. The interior of the cell behind it was four amos in measurement, and in the Second Temple it was six (amos). And perforce this Temple is the one of the future, because there was no wall separating the Holy of Holies in the Second Temple.
