40 was actually a very significant number in the bible.
the flood was 40 days and 40 nights
Noah then waited another 40 days before opening the ark after the flood
Moses was on the mountain with god for 40 days (this actually happened twice)
The Israelites spent 40 years in the wilderness, one year for each day they explored the Promised Land.
Jesus was seen in the earth 40 days after His crucifixion
A 40-something time period, whether days, months, or years is ALWAYS a period of testing, trial, probation, or chastisement (but not judgment) and ends with a period of restoration, revival or renewal.
