Seven

My "cloistered brothers" and I were reading Joseph's interpretation of Pharoah's dream, Gen. 41.  In this dream, there's seven fat cows and seven skinny cows and seven ears of healthy grain and seven of poor grain.

One of the "cloistered brothers" asked, "what's with the number seven?"

My explanation was just that numbers were important to the Hebrews and they had special ones to denote fortune.

But another "cloistered brother" added that when you're playing dice, you have more chances of rolling a seven, than any other sum:

6 + 1 = 7

5 + 2 = 7

4 + 3 = 7

3 + 4 = 7

2 + 5 = 7

1 + 6 = 7

Well, what do you know?  He's right.
