The Meaning of Numbers: The Number 7
Used 735 times (54 times in the book of Revelation alone), the number 7 is the foundation of God's word. If we include with this count how many times 'sevenfold' (6) and 'seventh' (119) is used, our total jumps to 860 references.
Seven is the number of completeness and perfection (both physical and spiritual). It derives much of its meaning from being tied directly to God's creation of all things. According to some Jewish traditions, the creation of Adam occurred on September 26, 3760 B.C. (or the first day of Tishri, which is the seventh month on the Hebrew calendar). The word 'created' is used 7 times describing God's creative work (Genesis 1:1, 21, 27 three times; 2:3; 2:4). There are 7 days in a week and God's Sabbath is on the 7th day.
The Bible, as a whole, was originally divided into 7 major divisions. They are 1) the Law; 2) the Prophets; 3) the Writings, or Psalms; 4) the Gospels and Acts; 5) the General Epistles; 6) the Epistles of Paul; and 7) the book of Revelation. The total number of originally inspired books was forty-nine, or 7 x 7, demonstrating the absolute perfection of the Word of God.
Appearances of the number seven
There are at least seven men in the Old Testament who are specifically mentioned as a man of God. They are Moses (Joshua 14:6), David (2Chronicles 8:14), Samuel (1Samuel 9:6, 14), Shemaiah (1Kings 12:22), Elijah (1Kings 17:18), Elisha (2Kings 5:8) and Igdaliah (Jeremiah 35:4).
In the book of Hebrews, written by the apostle Paul, he uses seven titles to refer to Christ. The titles are 'Heir of all things' (Hebrews 1:2), 'Captain of our salvation' (2:10), 'Apostle' (3:1), 'Author of salvation' (5:9), 'Forerunner' (6:20), 'High Priest' (10:21) and the 'Author and finisher of our faith' (12:2).
In Matthew 13 Jesus is quoted as giving seven parables (Matthew 13:3 - 9, 24 - 30, 31 - 32, 33, 44, 45 - 46, 47). Seven Psalms are ascribed to David in the New Testament (Psalm 2, 16, 32, 41, 69, 95 and 109).
In the book of Revelation there are seven churches, seven angels to the seven churches, seven seals, seven trumpet plagues, seven thunders and the seven last plagues. The first resurrection of the dead takes place at the 7th trumpet, completing salvation for the Church.
How is number seven linked with God's annual Feast Days?
There are 7 annual Holy Days, beginning with Passover and ending with the Last Great Day (the day after the Feast of Tabernacles ends in the fall). The cycle of the holy days is completed in 3 festival seasons by the 7th month of the sacred calendar: Passover and Unleavened Bread, 1st month; Pentecost, 3rd month; and Trumpets, Atonement, Tabernacles and Last Great Day, 7th month.
