מיתיבי חביתי כהן גדול לא היו באות חצאין אלא מביא עשרון שלם וחוצהו ותניא אילו נאמר מנחה מחצית הייתי אומר מביא חצי עשרון מביתו שחרית ומקריב חצי עשרון מביתו ערבית ומקריב ת"ל מחציתה בבקר מחצה משלם הוא מביא

An objection was raised: [We have learnt:] The meal-offering of the High Priest may not be brought in [two separate] halves, but he must bring a whole tenth and then divide it. And it has been taught: Had Scripture stated, 'For a meal-offering a half', I should then have said that he must bring a half tenth from his house in the morning and offer it, and a half tenth from his house in the evening and offer it; but Scripture states, 'Half of it in the morning', that is, he must offer half of the whole tenth!<span class="x" onmousemove="('comment',' Hence an objection against R.
