Reference for Shabbat 268:12
כי אתא רב דימי אמר רבי אלעזר הלכה כר"א בן עזריה
he said in R. Eleazar's name: The <i>halachah</i> is as R. Eleazar b. 'Azariah. In the West [Palestine] they pondered thereon: is the bathing of the whole body [permitted], or [only] the bathing of the membrum? Said one of the Rabbis, named R. Jacob, it is logical [that it means] the bathing of the whole body. For should you think, the bathing of the membrum, is this worse [less important] than hot water on a wound? For Rab said, One does not withhold hot water and oil from a wound on the Sabbath.<span class="x" onmousemove="('comment',' Whereas according to the present interpretation the first Tanna permits even sprinkling on the first day only, but not on the third.
