70

is a Pell number and the smallest abundant number which is not the sum of some subset of its divisors.

= 7 + 8 + 9 + 10 + 11 + 12 + 13
= 2(6²- 1²) = 2(6 + 1)(6 -1)

70² = 1² + 2² + 3² + 4² + ... + 22² + 23² + 24²

Symbolism:
70 corresponds to the totality of an evolution, an evolutionary cycle being fully completed, according to Saint Augustin.
The corresponding Hebraic letter is 'ain, which corresponded to the sixteenth mystery of the Tarot: the house-God, symbol of fall, collapse, catastrophe - there is agreement with the idea of termination of cycle, according to R. Allendy.

The 70 years of captivity of Babylonian of two of the twelve tributes of Israel. (2 Ch 36,21)
