Immediately, the Shekhinah gives [Var. there are aroused] three ‘voices’, towards the Faithful Shepherd, and says to him: ‘Rise O Faithful Shepherd! For about you it is stated: (Song. 5:2)... the voice of my beloved is knocking... towards Me – with His four letters.’
And He shall say through them: ‘... open-up for Me, My sister, My beloved, My dove, My‘completion’ (tam)...’ For behold: (Lam. 4:22) Completed (tam) is your sin, O daughter of Zion, He will not exile you again...’
(Song. 5:2)... for my head is full of dew....iiiSee Shemot Rabbah 33:3 What is the meaning of full of dew? But the blessed Holy One said: ‘Do you think that since the day the Temple was destroyed, that I have entered My house, and that I have entered in settlement? Not so! For I do not enter all the while you are in exile.’ivSee BT Ta’anit 5a
