Because Of Noah Moses And Jesus Why Is 40 A Special Number To God?

Answer 1

It is highly unlikely that a Supreme Being would show a special affinity for a random Arabic numeral.

Answer/

Due to God being omniscient, the number 40 written forty is used to describe a period of time relevant for the physical world according to Him, and is symbolic in Holy Scripture for a period of testing, for in the Revelation of John Chapters 21/22, there is no time and there is no curse and so no testing, for the physical world has passed away and men dwell in eternal life.

Since men are not omniscient, that completion of a physical period of forty is only known to God.

Answer 2

Twenty and its multiples are other favoured numbers. In '“There Was No King in Israel”: The Era of the Judges' (published in The Oxford History of the Biblical World, pages 139-140), Jo Ann Hackett points out that the number of years of peace brought about by each of the major judges, or the number of years of their ruling, is a multiple of 20, with the sole exception of Jephthah who ruled Israel for 6 years. Othniel's defeat of Cushan-rishathaim gave Israel 40 years of peace; after Ehud, 80 years of peace; after Deborah, 40 years; after Gideon, 40 years; then Samson is said to have judged Israel for 20 years. These numbers were no doubt fortuitous, as they helped the early tradents when passing the stories down orally before they were finally written down.

Jesus' 40 days in the wilderness is a separate case, being an allusion to both Elijah and Moses.
