"Teach us to number our days, that we may gain a heart of wisdom." Psalm 90:12

The number 10 is mentioned 242 times in the Bible, also has a special meaning of authority, completeness of order, and responsibility. Also in Genesis 1, God created 10 things on the first day and 10 things on the sixth and final day of creation, and He declared it all "good." 

Whenever we see the number 10 in the Bible, we see God's hand in his interaction with us through His divine authority and design. We can trust that everything God does is complete, in order, and very good_ Steppesoffaith.com
