Why is Para Aduma Chkas HaTorah? The only one Shlomo can’t decipher and that Hashem must reveal to Moshe.
Two levels:
Level One: Chuka means the norm, the norm is Ratzoi VaShov, each Mitzvah is either Ratzoi or Shov. Para Aduma is both.
Level Two: Chuka means Chakika (carved or engraved) which s Sovev. Para is ratzoi vaShov from Sovev and that is why Shlomo doesn’t know it etc.
The double הוי’ה reveals that we are speaking of הוי’ דלעילא. MP3
