[If] one slaughtered a pesach-offering and a chatas-offering for a designation other than their own, [or] he received [their blood], or conveyed [it], or threw [it] for a designation other than their own, or for their designation and for a designation other than their own, or for a designation other than their own as well as for their own designation — they are invalid. What is [an example of] ‘‘for their own designation and for a designation other than its own’’? For a pesach designation and a shelamim designation. What is [an example of] ‘‘for a designation other than their own as well as for their own designation’’? For a shelamim designation and for a pesach designation. For a sacrifice can be invalidated during [any of] four things: During slaughter, reception [of the blood], conveying [to the Altar], and throwing [upon the Altar]. R’ Shimon validates in [the case of] conveying. For R’ Shimon used to say: It is impossible [to make an offering] without slaughtering, receiving, or throwing [the blood]; but it is possible without conveying [it] — [because] one can slaughter [the offering] at the side of the Altar and throw [the blood there]. R’ Eliezer says: [If] one walks where he must walk, the intent invalidates, but if [one walks] where he need not walk, the intent does not invalidate.
