The Whole World Drinks From the Runoff of Eden

Yalkut Shimoni on Torah 22:3

Rabbi Yehoshua ben Levi said: the whole world drinks from the runoff of the Garden of Eden, as it is said, "And a river goes out from Eden" (Genesis 2:10) and so on. It was taught: from the runoff (of the Garden of Eden, which is sixty times more than the whole world, for one kor is thirty se'ah, and a se'ah is four kav), a field of a kor's size drinks a half-se'ah measure.
