Translation:Mishnah/Seder Kodashim/Tractate Kinnim/Chapter 2/1/Translation

An unspecified bird-pair from which a bird flew away,

or if it flew among those going to be put to death,

or if one of [the pair] died –

a partner should be taken for the second [bird].

If it flew among those going to be sacrificed –

it is invalid [for sacrifice], and invalidates [another] one corresponding to it;

For [the rule is that] a bird which flies [into another group] is invalid,

and invalidates one corresponding to it.
