As was already noted before on MiYodeya,
- the longest parasha (Naso) has 176 verses
- the longest Psalm (119) has 176 verses
- the longest tractate of Talmud Bavli (Bava Batra) ends on daf 176
Is there any significance to this coincidence?
(of course there is no coincidence, in Hebrew the letters for MiKReH, coincidence, also spell out Rak Me Hashem - only from God).
One very nice explanation I heard (and now found here and here) is that 176 equals 22 times 8. 22 is the number of letters in the Alef Bet (the complete Hebrew alphabet), 8 symbolizes "one beyond the natural" or "completeness beyond nature".
The product of two complete numbers is therefore the ultimate completeness and demonstrates completeness and perfection of Torah.
Are there other explanations or relevant sources?
