Chasidut su Ezechiele 7:78

And this is the aspect of Shabbat HaGadol, which is the name of the Shabbat before Passover, on account of the miracle, etc. The essence of the miracles and wonders that took place during the Exodus from Egypt - which crumbled the battles and nullified nature and revealed His Blessed Providence to the world - all of it was drawn from the aspect of Shabbat, which is the Future World which is totally Shabbat. From there, Hashem Yisbarach drew, so to speak, divine providence from the ends of the earth, etc., corresponding to (Ezekiel 7:2) "an end! The end has come", etc., as is brought there in the lesson as seen above. The essence of the Exodus from Egypt is drawn from Shabbat, which is the aspect of the World to Come. Therefore, Pesach is also called Shabbat, as it is written (Leviticus 23:15) "And you shall count for yourselves, from the morrow of the rest day"; in other words, Pesach, which our Sages of Blessed Memory said (Menachos 65b) that the essence of the power of the miracle of Passover is drawn from Shabbat, as explained above. This is the aspect of the Shabbat that is before Passover, which is called Shabbat HaGadol because of the miracle. For all of the miracles of the Exodus from Egypt were drawn from the aspect of Shabbat, as explained above. Therefore it is called "Gadol" because of the miracles which were called the aspect of Gadol (great), as it is written (II Kings 8:4) "Please tell me all the great things that Elisha performed". As Rabbeinu z"l wrote there in the lesson as seen above, 'And 2 tears went down into the great sea', see there.

And that which appears to me is from that which we say in the prayer of Rosh Hashanah, “And every created being will know, etc. and Your rulership is over all of the dominion (mashalah). And [the last word] is the initials of (Psalms 92:1), “A psalm – a song for the day of Shabbat (Mizmor Shir Leyom HaShabbat).” And likewise is it said (in the Shabbat morning prayers}, “This is the song of praise of the Shabbat day… ‘It is good to praise the Lord (Tov hehodot laShem)’ (Psalms 92:2)” – the explanation of the matter is that these three words are the three names [represented by], “He scatters frost like ashes (kefor ke’effer yifazer)” (Psalms 147:16, see Mekor Mayim Chayim on Baal Shem Tov, Vayigash 6:4): And that is that tov [has a numerical equivalent of] seventeen, which is the name of aleph-hay-vay-hay], the initials of et hashamyim ve’et haaretz (the heavens and the earth), which indicates the past. And the [four-letter] name of the Lord indicates the present. And hodu [has a numerical equivalent of] twenty-one (the name, aleph-hay-yod-hay), which indicates the future, as I have explained about the verse, “I will be what I will be” (Exodus 3:14). And this name indicates the ‘sweetening of harsh judgements’ at their root. And that is that when we observe all of the Creator’s oversight over all of His creatures; such that even if we do not feel the good now, nevertheless, good will come out of it in the future. And one who considers this will take good counsel from it, to accept everything with love – as he will not concentrate on the apparent bad, but rather on the good in the future. And through this, he will ‘bless the bad just like the good,’ and bring the thing back to its root. As above (in its roots), everything is good, such that the matter will automatically be sweetened. And understand this. For, in my humble opinion, this is the intention of Nachum, the man of Gimzo (Taanit 21a; see further, Parashat Tzav, p. 162.). And hence this name is composed of the letters, hey-vav-dalet-vav, an expression of raising, such as “his hand he shall place above (hadah)” (Isaiah 11:8); “voices raised joyfully (hed) on the hills.” For the matter must be raised to its root; and it will automatically be sweetened.
