Pesach – It’s Essence:
“And HaShem spoke to Moshe saying, ‘This month shall be the beginning of months for you.’ “
“‘… for you.‘ ” As a Nation – “only a free people, a Nation, has an independent calendar.” (Quoting Rabbi Yonah H. Geller, Congregation Shaarie Torah – Pesach 5764 [April 2004])
” ‘… for you.‘ ” Yochanan: but not for “them.” them: the idolators (followers of Rameses).
Shmoth 12.13 “And the blood shall be to you for a token upon the houses where ye are; and when I see the blood, I will pass over you, and there shall no plague be upon you to destroy you, when I smite the land of Egypt.”
12.23 “For the L-RD will pass through to smite the Egyptians; and when He seeth the blood upon the lintel, and on the two side-posts, the L-RD will pass over the door, and will not suffer the destroyer to come in unto your houses to smite you.”
HaShem Roi (Tehillim 23) – Just as a shepard at night guards the sheep in the sheep-fold by sitting in the doorway of the sheep-fold with his rod and staff, so too did HaShem guard Israel, His first-born on that “guarded night!”
What did Avinu Ya’acov do? Ya’acov built sheep-folds for his sheep; as it says, “Ya’acov journeyed to Sukkoth and built himself a house, and for his livestock he made shelters/sukkoth; he therefore called the name of the place Sukkoth.”
“And Joseph placed his father and his brethren, and gave them a possession in the land of Egypt, in the best of the land, in the land of Rameses, as Pharaoh had commanded.” (B’rashith 47.11)
And what does the passuk (Shmoth 1.11) say? “And the children of Israel built treasure cities for Pharaoh, Pithom and Rameses.”
HaShem Roi (Tehillim 23) – Just as a shepard leads his flock away from danger, so too did HaShem lead His flock away from the danger of “Rameses” (idolatry) to the protective shade of Sukkoth!
And what does the passuk (Shmoth 12.37) say? “And the children of Israel journeyed from Rameses to Sukkoth, about six hundred thousand men on foot, beside children.”
