Midrash su Zaccaria 4:3

R. Shimon b. Yochai says (Psalms 16:11) "sated (sova) with joys in Your presence": Rend it not "sova," but "sheva" (seven). To seven "joys" the faces of the righteous are likened in time to come: the sun, the moon, the firmament, the stars, lightnings, lilies, the menorah of the Temple: the sun and the moon — (Song of Songs 6:10) "beauteous as the moon, clear as the sun." the firmament and the stars — (Daniel 12:3) "The wise will shine like the radiance of the firmament, and the turners of the many to righteousness, like the stars, forever and ever." lightnings — (Nachum 2:5) "and they flash like lightning." lillies (Psalms 45:1) "For the chief musician, on the lillies." the menorah of the Temple — (Hoshea 14:7) "and his glory will be like the olive tree." And (Zechariah 4:3) "There are two olive trees over it (the Temple menorah), one at the right of the bowl and one at the left."
