Kabbalah zu Bereschit 2:10

Rabbi Elazar said that we have learned that whenever the term "These (Heb. אֵלֶּה)" appears, it always annuls something previously mentioned. Now, it is written in the portion of Beresheet, "And a river went out of Eden to water the garden; and from thence it was parted" (Gen. 2:10). This river (corresponding to Yesod) is drawn and comes out of Eden, (which is Chochmah), and enters the garden, (Malchut), to water it from the supernal waters and bring it pleasure, making it produce fruit and seed. This gives satisfaction to everyone. The garden is pleased which brings pleasure to the river. As it is written: "Because in it He rested" (Ibid. 3). And it is also written: "And He rested on the seventh day" (Ibid. 2) (He rested in the Garden that is Malchut). This is the secret of the matter, for it produces offspring, and no other Sefirah can produce any fruit.

Come and behold: from the day the world was created, Noah was destined to be joined in union with and to enter the ark. And until they were joined as one, the world had not reached a fully stable condition. And as soon as this occurred, it is written: "From these was the whole earth overspread" (Gen. 9:19). What is meant by "overspread", נָפְצָה? These words are analogous to the verse: "and from thence the river parted" (Gen. 2:10) (meaning that spreading out is similar to the supernal ark, which is the secret of the Garden). For from that point in the text onward, we find the separation and diffusion of progeny into all quarters of the world. (After they were perfected in the ark, they were able to come forth and exist in the world of separation without being annihilated, as was the generation of the Great Flood). And all is one and one is like the other. Therefore "These are the generations of Noah." "These" specifically. Only Yesod (the foundation) of the world

"For He has founded it upon seas" (Tehilim 24:2). There are seven pillars on which the earth supports itself, and which are seven seas (the seven Sefirot). The Sea of Kineret (Galilee) rules over them. Rabbi Yehuda said, Do not say it rules over them, but the Sea of Kineret is filled from them, "And established it on the rivers"(Ibid.) Which rivers are being referred to? It is written, "The floods have lifted up, Hashem, the floods (lit. 'rivers') have lifted up their voice" (Tehilim 93:3), as written, "And a river went out from Eden to water the garden" (Beresheet 2:10). Therefore, "He established it on the rivers."
