Chasidut su Genesi 36:12

Another reason for the need of the word ‎לאמור‎ to ‎appear in the verse under discussion: We have a ‎tradition that every word in the Torah preceded the ‎historical events described in the Torah, so much so ‎that they were recorded even before the universe had ‎been created. We must therefore fall back on the ‎statement of the Kabbalists that, essentially, the ‎written Torah is nothing but a record of the various ‎names of the Creator.

The ‎same applies when Moses commenced the song of ‎thanksgiving for the salvation of the Israelites from the ‎last and most dangerous threat of the Egyptians. We ‎are to examine this text in order to discover hidden ‎meanings

Behold, Itzchak is [the symbol of] the characteristic of Gevurah, and was more successful than Avraham [the symbol of compassion] and this is understood from what is written above, that this is the root of judgments, and through the fact that they bring the judgments to their source, [the judgments] are cancelled. [And this is] As we say, the judgments are only sweetened at their root, specifically. ...
