The number nine appears 49 times in the Bible and is used to symbolize divine completeness or finality. For example, Christ is said to have died on the ninth hour of the day.
The number nine appears prominently in Scripture as the number of judgment and finality. Because it is the final digit, it represents the conclusion of a matter. For example, nine generations exist between Adam and Noah, with the Flood as the final judgment. The number nine can also symbolize the nine fruits of the Holy Spirit found in Galatians, among which are faithfulness, gentleness, goodness and joy.
