How Long Is a Generation in the Bible?

The concept of a "generation" in the Bible is often associated with a period of approximately 40 years, though the exact length can vary depending on the context. In many biblical passages, a generation is linked to a specific time span, particularly in relation to the Israelites’ journey and God's covenant with His people.

Biblical References to Generations

One of the most common associations of a generation in the Bible is the 40-year period. For example, during the Exodus, God decreed that the Israelites would wander in the wilderness for 40 years as a judgment on their disobedience (Numbers 32:13). This period of wandering is often regarded as the length of a generation in the Old Testament.

In Psalm 95:10 (KJV), it is written: "Forty years long was I grieved with this generation, and said, It is a people that do err in their heart, and they have not known my ways." Here, the Bible refers to a generation as lasting 40 years, specifically pointing out the disobedient generation of Israelites.

Other Biblical Contexts

  • Family Generations: A generation can also refer to the span between the birth of parents and the birth of their children. For example, in the genealogy of Jesus Christ, Matthew 1:17 states, "So all the generations from Abraham to David are fourteen generations; and from David until the carrying away into Babylon are fourteen generations; and from the carrying away into Babylon unto Christ are fourteen generations."
  • Spiritual Generations: The term can be used in a spiritual sense, referring to a group of people sharing a common trait or characteristic. For instance, Matthew 12:39 refers to "an evil and adulterous generation" in Jesus' day.

Conclusion

In biblical terms, a generation is often considered to be around 40 years, especially when associated with the Israelites’ time of wandering in the wilderness or God’s judgment. However, the length can vary depending on the specific context, such as family generations or spiritual cycles.
