Halakhah su Levitico 22:11

The Tashbeitz also writes that even after the husband dies, the wife should continue practicing her husband’s family customs if the couple has children and she has not remarried. He bases this assertion on the Torah’s laws regarding a woman whose father is not a kohen eating terumah (kohen’s tithe; see Vayikra 22:11-13). If her husband is a kohen, she may eat terumah even after his death if the couple has children and she has not remarried.

From the laws of the commandment is that which they, may their memory be blessed, said (Gittin 12b) that a runaway slave of a priest eats priestly tithe, since he is his acquired property in any case. And so [too,] a rebellious wife, behold she eats; and any wife of a priest [may] eat, even if she is only three years and one day old. Also the betrothed of a priest would have been fitting to eat, except the Sages decreed that she not eat until they are married, as it appears in the beginning of the fifth chapter of Ketubot 57b. A Hebrew slave does not eat, as behold the Torah forbade both the perennial worker and the annual worker, as it is written (Leviticus 22:10), "the boarder of a priest and the hired worker may not eat the holy." But a Canaanite (gentile) slave eats, because he is his acquired property. Also, if the slave acquires other slaves they [may] also eat through him, since it is written (Leviticus 22:11), "when he acquires an acquired soul" - which has an implication that the acquired soul makes an acquisition. If, however, the second-tier slave acquires a third-tier slave, [the latter] may not eat. Since the [Torah] stated, "when an acquired soul makes an acquisition," and not "an acquisition of an acquisition." Any priestess who had intercourse with someone who disqualifies from the priesthood is permanently forbidden from eating priestly tithe (Yevamot 65a). The same is true for a hermaphrodite [priest], whether he had intercourse through his male organ or through his female organ. And even a stretched - and that is a person who stretched his foreskin so that he would appear as if he was uncircumcised - is rabbinically forbidden from eating until he is circumcised a second time (Yevamot 72a). And the rest of its many details are elucidated in Tractate Terumot.
