[If] this woman has one [pair of bird-offerings], this one has two [pairs], this one has three [pairs], this one has four [pairs], this one has five [pairs], this one has six [pairs and] this one has seven [pairs], [and one bird] flew from the first [group] to the second, [then one flew from the second] to the third, [then one flew from the third] to the fourth, [then one flew from the fourth] to the fifth, [then one flew from the fifth] to the sixth, [and then one flew from the sixth] to the seventh, [then one bird] returned [down the series of groups], it invalidates one [bird in the group it flies to and one in the group it flew from] as it goes [up through the series of groups] and one as it returns [back to the beginning of the series]. The first and the second [groups] do not have any [valid bird-offerings]; the third [group has one valid pair of bird-offerings]; the fourth [group] has two [valid pairs]; the fifth [group] has three [valid pairs]; the sixth [group] has four [valid pairs]; [and] the seventh [group] has six [valid pairs of bird-offerings].  [If one bird again] flew [in succession from each group into the next] and [then one bird again] returned [in succession from each group into the next, each bird which flies between the groups] invalidates one [bird in the group it flies to and one in the group it flew from] as it goes [up through the series of groups] and as it returns [back to the beginning of the series]. The third and the fourth [groups] do not have any [valid bird-offerings]; the fifth [group] has one [valid pair]; the sixth [group] has two [valid pairs]; the seventh [group] has five [valid pairs of bird-offerings].  [If again, one bird] flew [in succession from each group into the next] and [then again one bird] returned [in succession from each group into the next, then each bird which flies between the groups] invalidates one [bird in the group it flies to and one in the group it flew from] as it goes [up through the series of groups] and one as it returns [back to the beginning of the series]. The fifth and the sixth [groups] do not have any [valid bird-offerings]; the seventh [group] has five [valid pairs of bird-offerings]. And there are those who say that the seventh [group] did not lose anything [more as a result of these additional flights back and forth].  And if [a bird] flew from those [bird-offerings] which must be left to die into any of these [groups], then all of these groups of bird-offerings must be left to die.

[If there was] an undesignated pair [of obligatory bird-offerings] and a predesignated pair [of such offerings], [and a bird] flew from the undesignated pair to the designated pair, [then] he shall take a pair-mate for the second [bird of the undesignated pair]. [If a bird then] returned, or if [a bird] flew initially from the designated pair [into the undesignated pair], [then] they must all be left to die.
