Forty
'Forty' represents completeness because 'four' and 'ten' both mean what is complete. Forty is the product of four and ten. Compound numbers have a meaning similar to the simple numbers which compose them, and all numbers in the Word represent spiritual realities.

Arcana Coelestia #3434
3434. 'And he said, Because now Jehovah has made room for us' means increases of truth from there. This is clear from the meaning of 'a broad place' as truth, dealt with immediately above in 3433. 'Room being made' therefore is receiving increases of truth.
