(Un)lucky 7
When the number 7 pops up many think of the creation story when God made the world in six days and rested on the seventh day. Scholars have found that the number seven often represents perfection or completeness in the Bible.
Seven is also associated with gambling, as well as the following: There are seven planets. There are seven main colors in the rainbow. There are seven musical notes. The lunar phase continues for seven days. There are seven dwarfs that helped Snow White.
