How did this whole "Holy water vs Satan" thing start anyways?

water was associated with cleaning so it became associated with purity, baptism, and removing sins. that's why in recent media it's used as a weapon against satan. he's sin and flesh if you believe in the bible

No damn clue I wasn’t even here for it-

I'm not really sure but my parent use zamzam from our house cuz it's a bit haunted.
We hear and see many weird stuff O_O
