And this is: (Song. 4:12) A locked (na)’ul garden... and in it, a sealed wellspring – which is the Shekhinah, Yod י (=10) comprised of ten sephirot – the Yod of MeYTaTRON.
All the sephirot act through him Metatron, in this low world, and through him is: ‘levirate marriage’ and ‘removal’, and a bill of release divorce.
And all letters are ‘exchanged’ through him, such as M-Tz-P-Tz, and it is ‘the shutting (ne-)’ilah of festivals’, and of appointed times and holidays, ‘the shutting of the door to borrowers’.
