Reference for Menachot 31:14

But the Sages say, The penalty of kareth is not incurred unless he expressed the intention which makes piggul during the service of the whole mattir.<span class="x" onmousemove="('comment',' I.e., during all the three sprinklings.');">²⁰</span> Now here it states: 'If he expressed an intention which makes piggul either during the first [sprinklings] or the second or the third', and yet they differ!<span class="x" onmousemove="('comment',' The Sages holding that where the intention which makes piggul was expressed during the first sprinklings only, the others being performed in silence, the offering is not piggul. Apparently the principle, Whatsoever a man does in silence he does according to his first resolve, is not adopted; contra Rab.');">²¹</span>
