And accordingly, with this paradigm we can now also explain the straightforward explanation of the Possuk: “And it was when Pharaoh sent out the Jewish people.” (Which is not implying that he sent out the holy sparks which the B’nei Yisroel had elevated in Mitzrayim, but that he sent out the Jewish people themselves), because specifically after the ten plagues, and after the end of the servitude -which is the refinement of Mitzrayim-, was there the emergence of the possibility, and therefore also of the need for Pharaoh to send the Jewish people out of Mitzrayim.
This is because since all the holy sparks within Pharaoh had been refined and elevated, and because of the loftiness of those sparks devolved from ‘Tohu’, Pharaoh was left imbued with the power to send the B’nei Yisroel out from Mitzrayim.
Because after the conclusion of the Egyptian bondage, there were some members of the B’nei Yisroel who considered that it would be better to remain in the best part of the land of Mitzrayim, in the land of Goshen, and to serve HaShem in tranquillity, and consequently they did not wish to go into the desert where there would be snakes, vipers and scorpions in a land not sown (referring both to the literal and the spiritual sense as well).
