Key
All the keys hang not at one man’s girdle.
Better is the turn of the key than a friar’s conscience.Spanish.
Locks and keys are not made for honest fingers.German.
The golden key opens every door.Italian.
The key that is used grows bright.German.
The keys at the girdle—the dog in the larder.Spanish.
Your key fits not that lock.
