And the mystery of the matter: (Gen. 1:9) Let the waters be gathered, from under the heavens to one place... etc. ‘One’∞eḥad is Malkhut,... and let the dry land be seen – this is sel’a (rock) – Metatron, for whose sake it is stated: (Gen. 2:21)... and He took one of his ribs (tzel)’a, and He enclosed flesh beneath it...
What is flesh (basar)? It is that of which it is stated: (Gen. 6:3)... in that also he is (beshagam) flesh... And until he Moses caused Her to descend, the ‘rock’ did not ascend and did not give its waters.
