In the book of Matthew the number 14 is used to group the generations of patriarchs from Abraham to Christ. The Bible uses the prime number 3 to establish 3 groups of 14 generations.
Matthew 1:17
"17 So all the generations from Abraham to David are fourteen
generationsand from David until the carrying away into Babylon are; and from David until the carrying away into Babylon are fourteen
generationsand from the carrying away into Babylon unto Christ are; and from the carrying away into Babylon unto Christ are
fourteen generations."
Therefore, there are a total of 42 generations from Abraham to Christ
(14+14+14=42).
The number 14 is related to the prime number 7 (7+7=14).
