For true bible authenticity – that is keeping to how the text was originally written, the following verses should mention piss:
“So and more also do God unto the enemies of David, if I leave of all that pertain to him by the morning light any that pisseth against the wall”
“But Rabshakeh said unto them, Hath my master sent me to thy master and to thee, to speak these words? hath he not sent me to the men which sit on the wall, that they may eat their own dung, and drink their own piss with you?”
2Kings18:27 and Isaiah36:12
“And it came to pass, when he began to reign, as soon as he sat on his throne, that he slew all the house of Baasha: he left him not one that pisseth against a wall, neither of his kinsfolks, nor of his friends.”
Thank goodness for modern public conveniences.
