There are usages that we may think are far fetched but our Sages teach that they may be primary functions intended by Hashem , the Creator & Designer.
The Torah , 21:14 , instructs every soldier to have a shovel among his tools & weapons ( in order to dig & cover up body wastes ).
The Talmud, Kesubos 5b , explains another level - Hashem has provided people with two toolboxes filled with a variety of equipment of different sizes & shapes. You can look at your two hands right now to see how each finger is uniquely shaped for many functions.
Thus the Talmud reveals an amazing secret - one of the primary purposes of our fingers are to serve as earplugs in order to block out inappropriate words.
We have two related levels of interpetation
1 - keep your area clean
2- keep your mind also clean.
Now may be a good time for a gem of Torah study.
