Commentary for Kiddushin 138:15

והכתיב (עזרא ב, סג) ויאמר התרשתא להם אשר לא יאכלו מקדש הקדשים בקדש הקדשים הוא דלא יאכל הא כל מידי ניכול

So now too [ye may partake] of the sacred food [consumed] in the country.<span class="x" onmousemove="('comment',' But not sacrifices. This shews that 'they were deemed polluted' means that they were accounted halalim, who may not partake of sacrifices.');">¹⁷</span> But on the view that we promote from terumah to family purity,<span class="x" onmousemove="('comment',' If a priest is seen eating terumah in his town, where he is known, we assume that he is of pure descent, and permit another priest to marry his daughter.');">¹⁸</span>
