What is the biblical reference for the number seven?

God chooses the number seven to be the only perfect number. There are seven days in the creation of the universe. The seventh day was one to rest and take in the joy of what has been created. (The book of Genesis) The number seven in both New and Old Testaments means the same as perfection. This comes from the creation story which is put into a seven day framework to emphasize the perfection of God's creation and the most perfect day of the week was the seventh day, the Sabbath. Throughout The Bible, there will be examples of the number 7 used this same way. In the new testament, one of the apostles asks Jesus if he has to forgive his brother 7 times and Jesus answers: I say seventy times seven times. This would mean an infinite number.
