The Meaning of Numbers: The Number 15
The number 15 in the Bible pictures rest, which comes after deliverance, represented by fourteen. The 15th day of the first Hebrew month (Nisan) is the first day of the Feast of Unleavened Bread, a day of rest for the children of Israel (and for Christians). The 15th day of the seventh Hebrew month begins the Feast of Tabernacles, also a day of rest.

Additional info on Biblical Meaning of Number 15
For Christians, the first day of the Feast of Unleavened Bread (Nisan 15) pictures rest from their sins, having had them removed by Christ's shed blood on Passover. The 15th day of the 7th month begins the Feast of Tabernacles. For the children of Israel, it pictured rest from the long harvest season. They were to dwell in booths in remembrance of their trek in the wilderness.
Prophetically, the 15th day of the 7th month pictures the coming Millennium when the world will have rest from sin because of the binding of Satan on the Day of Atonement. Under Christ's reign, salvation will then be offered to the world, becoming the great spiritual harvest of God for 1,000 years.
