It was a normal day when I got the box came in the post. I opened it and found a handful of objects inside. I picked out a piece of paper and on it was a riddle:

> The next clue lies within the top rung of me  
I am controlled by the 6
The key to me is found within this box  
I will lead to the richest treasure you will ever know  
Use the key, and you will gain the knowledge to solve this  

Fishing through the box, John also found a pendant:

![The star of David][1]

He also found a small object. It was a transparent hollow tube with a piece of paper inside. The paper had written on it `you`. John turned over the tube and found in small bumps the letters `7nAZqPqlz1M`

Where is the next clue, and in which country can it be found?
