A: First off, let me begin by saying that I think we need to be careful about searching for hidden messages, meanings, or codes in certain significant numbers in the Bible. If you put the word “Numerology” in a Google search, what you get for a definition is: “The branch of knowledge that deals with the occult significance of numbers.” Hence, “numerology” is associated with such things as the occult, the paranormal, astrology, paganism, divination, and wiccans.” But, if we put “Biblical” in front of “numerology” (“Biblical Numerology”), this is then supposed to make searching for the significance of number meanings in the Bible acceptable.

     Now, I am not saying that there isn’t some significance to certain numbers in the Bible, all I am saying is that we should be careful about trying to interpret what these meanings are. Ultimately, I believe God did have reasons for using certain numbers over and over in the Bible, but only He may know the true reasons. Having said this, I do think it is fascinating to see how many times certain key numbers are used over and over in the Bible. In six studies, we will be looking at how six of what I believe are the most key numbers in the Bible are used: 3, 6, 7, 10, 12, 40.

     The final number we will look at is the number “40.” This number is used 159 times in the Bible. Those who assign meaning to this number are generally agreed that it is a number symbolizing trial, testing, or judgment. This certainly seems to be borne out in a number of places in the Bible, however, it also is used for more than that. Let’s first look at the ways it could be taken as a number signifying trial, testing, or judgment, then we will look some other significant uses.

Trial, Testing, Or Judgment:

When God destroyed every living thing on the Earth by flood, it rained 40 days and 40 nights (Gen 7:4,12,17).

Three men in the Bible fasted 40 days and 40 nights: Moses (Ex 34:28)(Deut 9:9,18,25)(Deut 10:10), Elijah (1 Kin 19:8), and Jesus (Mt 4:2)(Lk 4:2)(Mk 1:13).

One of those spies was Joshua, and he was forty years old when he went (Josh 14:7).
