“Numbers in the Bible are often not meant to be taken literally, but serve a symbolic function. Our suspicions are aroused especially with a number that recurs so frequently as 40. What would be the symbolic meaning of the number 40? On one level, it represents a longer period of time, but there is more. The longer time has content: It is a time of need, of struggle, of testing. There is in fact extra-biblical evidence for this usage as well. But in the Bible, a third level of meaning appears. Forty denotes a period of preparation for some special action of the Lord; it is a time of grace.”
