What is the spiritual meaning of the number 9?

Used 49 times in Scripture, the number 9 symbolizes divine completeness or conveys the meaning of finality. Christ died at the 9th hour of the day, or 3 p. m., to make the way of salvation open to everyone. The Day of Atonement (Yom Kippur) is the only one of God's annual Feast days of worship that requires believers to fast for one day. This special day, considered by many Jews to be the holiest of the year, begins at sunset on the 9th day of the seventh Hebrew month (Leviticus 23:32).

Nine also represents the fruits of God's Holy Spirit, which are Faithfulness, Gentleness, Goodness, Joy, Kindness, Long suffering, Love, Peace and Self-control (Galatians 5:22 - 23).
