Halakhah su Esodo 12:12

"And the Lord took us out of Egypt" - not through an angel and not through a seraph and not through a messenger, but [directly by] the Holy One, blessed be He, in His glory, as it is stated (Exodus 12:12); "And I will pass through the Land of Egypt on that night and I will smite every firstborn in the Land of Egypt, from men to animals; and with all the gods of Egypt, I will make judgments, I am the Lord."

It is from the roots of the commandment [that it is] because Israel is the nation that God chose from all the other nations for His service and to recognize His Name, and they are not under the rule of the constellations that God apportioned to all the other nations. They are instead [directly] under the hand of the Holy One, blessed be He, without any intermediary of an angel or constellation; and as it is written (Deuteronomy 32:9), "For the portion of the Lord is His people, Yaakov is the measure of His inheritance." And as you find when He took them out from Egypt - which was a miracle that included all the people - that He took them out by Himself in His glory. And [this is] as they, may their memory be blessed, expounded, "'I will pass through Egypt' (Exodus 12:12) - I and not an angel; 'and I will strike the first-born' - I and not a seraph," as it appears in the Haggadah. And therefore anytime Israel maintains the Torah and crowns themselves with His service, only goodness will rest upon them, and the flow of blessing and a pure benevolent spirit will support them; and the opposite - the curse and the 'dedication' - will [rest] upon their enemies and haters. As such, if one of their tempers become short and he pronounces an expression of curse and 'dedication' on his money or his lands - which are under the blessing - the verse informs that it is impossible to remove it from the domain of the blessed to another domain. [This is] since everything that belongs to Israel - who is the portion of God - is His; [as] whatever a slave acquired, his master acquired (Pesachim 88b). Still, since we truly know that the intention of the one who dedicates is to remove that thing from his domain, it is fitting to fulfill his will; and [so] it returns to the domain of his Master and it becomes holy.
