A man is believed to say, "My father said to me that this family is impure"; "This family is pure"; "We ate in the ketzitzah of Plonit [see Lieberman: a ceremony for when one of the men married a woman who was not fitting for him]"; "Ploni's teacher said to him, 'Go and immerse your terumah!'"; or "We used to bring terumot and tithes to Ploni"—they are believed to give to him [his portion] but not as a grounds to presume he is a priest [for the purpose of passing on that status to his children]. But [if they testified] "Others used to bring to him [his portion]", they are not believed (although, Ehrfurt: they are believed). If [they testified] "He was a Gentile and converted", "A slave and he was freed"—then these are not believed. They are not believed to say, "I remember that Ploni owed Plonit (Ehrfurt: Ploni) a maneh"; or "Ploni's path went through Ploni's field" since this is like monetary cases. Rabbi Yohanan ben Berokah says: They are believed.

Said Rabbi Yohanan ben Berokah: A wife or minor is believed to say "From here the bee swarm left". When does this apply? When they are testifying right there. But if they go out and come back, they are not believed, since they only say this because of persuasion and fear [that people with power over them have instilled in them]. Men, wives, slaves and minors are believed to say "This place is impure" or "This place is pure".
