Word for numbers with special meaning (particularly Bible)

Numbers in the Biblical text often have archetypal meanings. For instance, 40 is a cycle (40 days of the Flood to wipe out the world, 40 years traveling in the desert to wipe out the prior generation of Israelites, etc.). There is a word for these representative, archetypal numbers in the Bible but it is currently alluding me.

Solution 1:

After more searching, I believe the technical term is 'typological number', 'archetypal number', or 'formulaic number'. Though 'typological' has additional meaning when relating to Christian theology and the relationship of the New and Old Testaments.
