The number 7 is typically associated with the concept of completion. The number 7 is used over 700 times in the Bible and 54 times in the book of Revelation alone. The work of creation was completed in 7 days. It took 7 days for the consecration of Aaron and his sons had to be completed so that they could enter into their duties as priests (Lev. 8:31-46) and on the day of atonement the priest sprinkled blood on the mercy seat 7 times (Lev 16:14) as a picture of the completed work of redemption that would be made in Christ.
