Chasidut su Esodo 12:42

1. This corresponds to “a night of guarding” (Exodus 12:42) - of guarding from harmful powers. Yalkut Shimoni II 210. These harmful powers correspond to natural sciences, to judgments, to the nations which harm the world. Then, on the night of the exodus from Egypt, when nature was eliminated specifically at night in order to break and eliminate the power of night, corresponding to natural sciences, therefore that night was guarded from all harm for powers, from all judgments, since providence was revealed, through which all harm and all judgments are eliminated.

Exodus 12,42. “that night will remain a ‎night of remembrance for Hashem, etc.” ‎Although it is a rule that G’d watches over Israel ‎benevolently constantly, and that He had equipped the ‎Israelites with positive as well as with negative ‎commandments so that non deserving (worlds) nations ‎would not share the benefit from His acts of kindness ‎for the Israelites by default, at this point in history ‎when the Torah had not yet been given to the people of ‎Israel, G’d had to perform His acts of kindness directly, ‎‎-not through emissaries, angels, to make certain that ‎they would benefit only the people for whom they were ‎intended. These considerations have been hinted at in ‎the words of our verse that G’d’s acts on behalf of ‎Israel during the night of the Exodus were of an ‎extraordinary nature. This idea has also been alluded ‎to in the Midrash which states: “I have kept in ‎mind for all these years the commandment performed ‎by the ‘old man,’ Avraham, who was the first person ‎taking action to prevent the negative forces in the ‎world from benefiting from G’d’s largesse. Prior to ‎Avraham’s appearing on the scene, G’d personally had ‎to see to it that the totally undeserving souls did not ‎benefit from His benevolence through a spillover from ‎the deserving. (Yalkut Shimoni Vayikra 18?)‎
