And this is the meaning then of וְיִתֶּן לְךָ that our Sages have said implies 'HaShem will give and then HaShem will give again'. The first giving is the ‘Hamshocha’ below of the ‘Hehlam Hoatzmi’, (וְיִתֶּן לְךָ הָאֱלֹקִים) in order to refine refinements, and then the giving again is this drawing down and revelation of the essence which is achieved as a result of the 'Avoidas Habirurim'.
As a result of וְיִתֶּן לְךָ הָאֱלֹקִים drawing down the ‘Hehlam Hoatzmi’ in both of the aforementioned ways (He will give and then he will give again) there is an outpouring of both the "Dew of Heaven" and also the "Fats of the earth." This symbolizes both the Torah and the Mishnah. But also to be taken literally to mean from the 'Dew of the heavens', for dew never gets held back (and especially as at no time was there ever even a thought to G-d forbid withhold) as well as literally the 'fats of the earth, with an abundance of grain and wine' and with the ultimate abundance, to include the third 'Beis HaMikdosh' as in Ya'acov who is called 'Bayis' and from there light is emitted to the whole world, thus making the whole world into a dwelling place for HaShem Blessed be He.
Glossary and Explanations
Avodah: A person serving HaShem. In his spiritual quest.
Defined by parameters: Which is why it can also reveal itself to much lower levels too.
Even more: Then its revelation is in order to refine the refinements.
וְיִתֶּן לְךָ: Which is written with the addition of the letter 'Vov' before the word 'Yiten' meaning 'And He will give' the 'And' being in addition to the giving.
וְיִתֶּן לְךָ הָאֱלֹקִים: A revelation from the name 'Elokim’, the supernal emotive attribute of 'Gevurah - Severity', which its remit in essence is to elevate.
Giving again: A second giving.
Avodas Habirurim: And as a result of it, and it is the revelation and exalted Divine extension, even greater than the first giving, which was for the purpose of the 'Avoidas Habirurim’.
He will give: Revelation in order to refine refinements.
He will give again: Revelations that come as a result thereof.
Fats of the earth: According to the explanation of the Midrash, that this refers to 'Torah'.
Mishneh: This is the answer to the question; what is gained with these blessing for Torah considering that the B’nei Yisroel were going to receive the Torah anyway – what is gained is that the 'Torah' will be drawn down and revealed from the 'Concealed Essence', which as explained earlier, is drawn down specifically through toil and conscientious study, but does not come with the 'Torah' on its own.
Dew never gets held back: Is never ever held back, differently from rain, which sometimes falls and sometimes is held back.' The Rebbe RaShaB writes that Eliyohu Hanovi brought down rain because the rain stopped but was not able to bring down dew because the dew never stopped.
Withhold: There is not even a הווה אמינא to withhold the abundance and the blessing.
Abundance of grain and wine: With material abundance as is its straightforward explanation.
Beis HaMikdosh: Which is particularly connected with Ya'akov Ovinu, like the maxim of our sages of blessed memory.
From there: From the Beis Hamikdosh, From the Temple.
