Reference for Yoma 53:12

וערכו שנים בני אהרן שנים הכהנים שנים למדנו לטלה שטעון ששה

Now only the bringing of the limbs to the ramp requires a priest, but not the bringing of the logs of wood, implying that the putting in order of the two logs of wood requires a priest.<span class="x" onmousemove="('comment',' Since the fetching of the wood is especially stated to need no priest, the inference is - obvious that the putting in order of the two logs requires a priest's service.');">¹³</span> Why, then, is it necessary to state 'And they [the priests] shall lay [the pieces] order'?
