OK, found it and yes, it does say pisseth against the wall but the context has to do with the sin and worship of idols from the house of Jeroboam and not having to do with pissing or even a literal interpretation of scripture. God is angry for these folks that have sinned and have convinced others to sin and he has indicated the wrath against them. But if you read on, you see that his graciousness is towards those who are believing and he does save them from his wrath.
9But hast done evil above all that were before thee: for thou hast gone and made thee other gods, and molten images, to provoke me to anger, and hast cast me behind thy back:
10Therefore, behold, I will bring evil upon the house of Jeroboam, and will cut off from Jeroboam him that pisseth against the wall, and him that is shut up and left in Israel, and will take away the remnant of the house of Jeroboam, as a man taketh away dung, till it be all gone.
Yet another preacher that decides to interpret the scripture from centuries ago, the stories told and try to apply them to our times and out lives word by word, letter by letter. I think his method of preaching is just to make himself look very knowledgeable and important...didn't work for me!
