Musar for Yoma 108:2
ושתיה היתה נקראת תנא שממנה הושתת העולם תנן כמאן דאמר מציון נברא העולם דתניא רבי אליעזר אומר עולם מאמצעיתו נברא שנאמר (איוב לח, לח) בצקת עפר למוצק ורגבים ידובקו
AND IT WAS CALLED SHETHIYAH: A Tanna taught: [It was so called] because from it the world was founded.<span class="x" onmousemove="('comment',' Tosef. II. The suggestion is that Zion was created first, and around it other clods, rocks, formations, continents, were formed until the earth was completed.');"><sup>3</sup></span> We were taught in accord with the view that the world was started [created] from Zion on.
Shenei Luchot HaBerit
The sages also describe G–d as having gathered a little dust from every part of the globe so that wherever man would die, the local earth would not reject his remains since he contained part of it (Rashi Genesis 2,7). Both statements are accurate and point us in the same direction. It is well known that Adam incorporated within him all subsequent generations of mankind, for their very existence was through him. Our sages described all subsequent mankind as being related to Adam either through his head, his eyes, his hair, etc. [In present-day parlance this means that all of our genes were at one time part of the genes of Adam.] Even in death man is not totally severed from his connection with original man: the earth Adam was made of was holy soil, from the site of the earth of the altar mentioned. That piece of earth in turn contained earth from all parts of the globe, seeing that this site is the site from which the whole earth receives its sustenance. Had Adam not sinned he would have lived forever. Since he sinned, however, and was expelled from the garden of Eden because G–d did not want him to eat from the tree of life and live forever, he was bound to die sometime.
