. If one designates a chatas and it is [now] blemished, he sells it and brings with its proceeds another [chatas]. R’ Elazar the son of R’ Shimon says: If the second [chatas] was offered before the first was slaughtered, [the first chatas] must be left to die, for the owner has already received atonement.

How does one use subterfuge regarding a bechor? [Concerning] an animal that was pregnant with her first offspring, one declares, “What is in this one’s womb, if [it is] a male, it is an olah,” [if] she gave birth to a male, it is offered as an olah. And [if he declares,] “If it is a female, it is a shelamim-offering,” if she gave birth to a female, it is offered as a shelamim. [If one declares,] “If [the fetus] is a male, it is an olah, and if [it is] a female, it is a shelamim-offering”: [If] she [then] gave birth to a male and a female, the male is offered as an olah, and the female is offered as a shelamim.

If she gave birth to two males, one of them is offered as an olah, and the second one is sold to those who have an olah obligation, and its proceeds are chullin. If she gave birth to two females, one of them is offered as a shelamim, and the second one is sold to those who have a shelamim obligation, and its proceeds are chullin.  [If] she gave birth to a tumtum or an androgyne, Rabban Shimon ben Gamliel says: No sanctity takes effect upon them.

If one declares, “The fetus of this [pregnant ani-mal] is an olah, and she herself is a shelamim,” his declarations stand. [But if he declared,] “[The pregnant animal] is a shelamim and her fetus is an olah,” [the fetus] is the offspring of a shelamim; [these are] the words of R’ Meir. R’ Yose said: If he intended to [say] this from the outset, since it is impossible to utter two designations simulta- neously, his declarations stand. However, if after he declared, “This [pregnant animal] is hereby a shelamim,” he [then] reconsidered and declared, “Her fetus is an olah,” [the fetus] is the offspring of a shelamim.
