Devarim 23:14 states that when you camp during a battle, you should keep a spade with you so that you can use it to cover up your excrement.
Since the Torah mentions the importance of "bodily cleanliness" when you're out in the field in battle, I wonder if there is any halacha learned from this verse or otherwise specifically regarding the position of a toilet seat after you are finished in the bathroom. Offhand, since the verse mentions "covering", to me it seems proper to close the toilet seat cover as a sense of cleanliness.
Is there any ruling that can be extracted from this verse, or is there any other recommendation cited by anyone even if it doesn't use this verse?
