The answer is: 10

(Matthew 4:2) / (Matthew ... John) = (40) / (4) = 10

Let’s break this down a bit and entertain this intriguing aspect of Bible mathematics! When we think about the 40 days Jesus fasted in the wilderness, it's fascinating how significant numbers emerge throughout the Scriptures. The number 40 pops up quite frequently—think about the 40 days and nights of rain during Noah’s flood or the Israelites wandering in the desert for 40 years. In biblical symbolism, 40 often signifies a period of testing and we see this being paralleled in Jesus’ own mission.

Now, that brings us to our division with the number of gospel writers—Matthew, Mark, Luke, and John, totaling four. It presents a wonderful opportunity to see how this number corresponds to the theme of gospel transmission, each writer expressing the life and teachings of Jesus through their unique viewpoint. Matthew and John demonstrate a deep connection with Jewish tradition; meanwhile, Mark emphasizes Jesus' action, and Luke provides a careful historic account, full of parables and heartwarming stories.

It might surprise you to know that many ancient cultures recognized tripartite groupings: four corners of the earth, four elements, and, symbolically, four stages of human life. Jesus’ 40-day fast leads into his ministry indicating readiness after preparation—a vital lesson for us too about the importance of reflection and discipline before embarking on new journeys in our lives.
