Tractate Zevachim - Chapter 6 - Mishnah 7 זבחים פרק ו׳ משנה ז׳

If he nipped a hatat of a bird for the sake of something else; if he drained out its blood for the sake of something else, or for its own sake and for the sake of something else, or for the sake of something else and for its own sake, it is unfit. An olah of a bird is fit [in such circumstances] except that it does not count for its owner’s obligation. A hatat of a bird or an olah of a bird which he nipped, or drained out the blood [with the intention] to eat what was normally eaten or to burn what was normally burned outside of the appropriate place, is invalid, but it does not involve karet; After the appropriate time, it is piggul and involves karet, Provided that the mattir was offered in accordance with the regulations. How does he offer the mattir according to regulations? If he nipped it in silence and drained the blood [with an intention of] after the appropriate time; or if he nipped it [with an intention of] after the appropriate time and drained the blood in silence; or if he nipped it and drained the blood [with an intention of] after the appropriate time: in these cases he offered the mattir according to regulation. How does he not offer the mattir according to regulation? If he nipped it [with an intention of] outside the appropriate place and drained the blood [with an intention of] outside the appropriate time; or if he nipped it [with an intention of] after the appropriate time and drained the blood [with an intention of] outside the appropriate place; or if he nipped it and drained the blood [with an intention of] outside the appropriate place; or if he nipped a hatat of a bird for the sake of a different sacrifice and drained the blood [with an intention of] after the appropriate time; or if he nipped it [with an intention of] after the appropriate time and drained the blood for the sake of a different sacrifice; or if he nipped it and drained the blood for the sake of a different sacrifice: in these cases he did not offer the mattir according to regulation. [If he intended] to eat as much as an olive outside the appropriate place [and] as much as an olive the next day, [or] as much as an olive the next day [and] as much as an olive outside the appropriate place; Or half as much as an olive outside the appropriate place [and] half as much as an olive the next day; Or half as much as an olive the next day [and] half as much as an olive outside the appropriate place, [the sacrifice] is unfit, and does not involve karet. Rabbi Judah said: this is the general rule: if the [wrongful] intention of time precedes that of place, [the sacrifice] is piggul, and involves karet; but if the [wrongful] intention of place precedes that of time, it is unfit and does not involve karet. But the sages say: in both cases [the sacrifice is] unfit and does not involve karet. [If he intended] to eat half as much as an olive [outside the appropriate place or after the appropriate time] [and] to burn half as much as an olive [similarly] it is fit, for eating and burning do not combine.
