יִ֭שְׂבְּעוּ עֲצֵ֣י יְהוָ֑ה אַֽרְזֵ֥י לְ֝בָנ֗וֹן אֲשֶׁ֣ר נָטָֽע׃
Gli alberi dell'Eterno hanno il loro riempimento, i cedri del Libano, che ha piantato;
Zohar
It was taught in the Mishnah that four times an hour every day, Eden drips upon the garden. The result of these drops is a river which separates into four branches. Each day, 48 drops fall on the seventy trees in the garden, as it is written, "The trees of Hashem have their fill" (Tehilim 104:15). Rabbi Tanchum said, It is written, "He waters the hills from His upper chambers" (Ibid. 13). What is his upper chamber? It is Eden. And where is Eden? Rabbi Yehuda said, It is above Aravot (sweet firmament). Rabbi Yosi said that it is in Aravot, where are treasures of good life, blessing and peace, and the souls of the righteous, as was taught. This is the upper chamber, while the Garden of Eden is lower, and an earthly garden is in apposition and draws from it daily.
