Yevamot 99B

ואינן מטמאין למתים. ואינן נושאין נשים, בין כשרות בין פסולות. הגדילו התערובות ושחררו זה את זה ⁠— נושאין נשים ראויות לכהונה.

And they may not become ritually impure with impurity imparted by a corpse, as each of them might be a priest. And they may not marry women, whether unflawed women, who may not marry a slave, or women unfit to marry into the priesthood, as with regard to each of them it is uncertain whether he is a priest or a slave. If the mixed sons matured and freed each other, they may marry women fit to marry into the priesthood, as a freed slave may marry such women. However, neither may marry a woman unfit for the priesthood, in case he is a priest.

ואינן מטמאין למתים, ואם נטמאו ⁠— אינן סופגין הארבעים. ואינן אוכלין בתרומה, ואם אכלו ⁠— אינן משלמין קרן וחומש. ואינן חולקין על הגורן. ומוכרין את התרומה, והדמים שלהן.

And they may not become ritually impure with impurity imparted by a corpse, since they are uncertain priests. However, if they became impure, they do not receive the 40 lashes, as each of them might not be priest. And they may not partake of teruma, as one of them is not a priest. However, if they ate teruma unwittingly they do not pay the principal and the additional fifth, as each of them might be a priest. And they do not receive a share of teruma in the granary, as neither can prove that he is a priest. However, they may sell the teruma that they remove from their own produce, and although they may not eat it, the money is theirs. Since it cannot be proven with regard to either of them that he is not a priest, teruma cannot be appropriated from them.
