Midrash su I Cronache 28:19

GEMARA: What were the great improvements? R. Elazar said that [they were] similar to those which we have learned in the following Baraitha: "The women's compartment was formerly without a balcony, but they surrounded it with a balcony and ordained that the women should sit above and the men below." Our Rabbis were taught: Formerly the women were sitting inside the Temple court and the men outside; but thereupon some levity resulted, and it was ordained that the women should sit outside the Temple Court and the men within; but still levity arose, and it was ordained that the women sit above (upon a balcony) and the men below. How could they do so? Does not the passage say (I Chr. 28, 19) All was put in writing from the hand of the Lord, who gave me instruction respecting all the works of the pattern. R. Joseph said: "They found another passage (Fol. 5'2) and interpreted it. (Zech. 12, 12) And the land will mourn, every family apart by itself, the family of the house of David apart, and their wives apart. And they said: 'Can this not be deduced through a fortiory, namely: If in the Messianic future, when Israel will be occupied in mourning, during which time the evil inclination is powerless of indulgence, it is, nevertheless, said that women and men should be separate; how much the more [should they be] in the Temple, where the people are occupied in rejoicing, where the evil inclination possesses the power of indulgence.'"
