[If there was] a chatas bird and an olah bird, as well as an undesignated pair and a designated pair —- [if] he made all of them above [the Red Line], half [of each of these pairs] is valid and half [of each of these pairs] is invalid; [if] he made all of them below [the Red Line], half [of each of these pairs] is valid and half [of each of these pairs] is invalid. [If] he made half of them above [the Red Line] and half of them below [the Red Line,] none is valid except for the undesignated pair, and that [pair] is divided between them.

[If] chatas birds mingled with obligatory pairs, only the number of chatas birds in the obligatory pairs are valid. [If] the [bird-offerings in the] obligatory pairs [were] twice as many as the chatas birds, half [of the offerings] are valid and half are invalid. But [if] the chatas birds were twice as many as the [bird-offerings in the] obligatory pairs, [the number of offerings equal to] the number of birds in the obligatory pairs are valid.  Similarly, [if] olah birds mingled with [an equal number of bird-offerings in] obligatory pairs, only the number of olah birds in the obligatory pairs are valid. [If] the [bird-offerings in the] obligatory pairs [were] twice as many as the olah birds, half [of the offerings] are valid and half are invalid. [If] the olah birds [were] twice as many as the [bird-offerings in the] obligatory pairs, [the number of offerings equal to] the number of birds in the obligatory pairs are valid.
