פסחים ה׳:א׳ - ה׳:ב׳

תמיד נשחט – the daily whole offering made at the time between the beginning of the decline of the sun and sunset (i.e., afternoon) is slaughtered all the rest of the days of the year at the eighth and one-half hour [of the day] (=2:30 pm). For the time of the slaughter of the daily whole offering is from when the shadows of the evening decline which is from six and one-half hours (=12:30 pm) as the sun declines to the west, as for half of the sixth and half of the seventh [hours], it (i.e., the sun) stands in the middle of the firmament. And the shadow does not decline other than the shadow of each person underneath it. And we make the slaughter [of the sacrifice] later by two hours after its time because of the vows and donations for it is impossible to offer them after the daily whole offering of the afternoon, as it is written (Leviticus 6:5): “and turn into smoke the fat parts of the offerings of well-being.” On the daily whole offering of the morning, he completed all the sacrifices entirely, so that there should not be anything later than the daily whole offering of the afternoon. And even on Shabbat where we do not offer vows and donations, we make the time of the slaughtering of the daily offering later because of the habit of vows and donations of the weekday. And on the Eve of Passover, when the Passover offering is made after the daily whole offering of the afternoon is sacrificed, we advance it one hour and do it at seven and one-half hours (=1:30 pm).

חל להיות בע"ש – for there is also the roasting of the Passover sacrifice that does not override the Sabbath, and one must roast it while it is still daylight, we advance it establish it according to the law that it would be slaughtered at six and one-half hours (=12:30 pm).

וקרב בשבע ומחצה – the completion of its offering is at seven and one-half hours (1:30 pm) for we tarry one hour while performing this ritual.

ששחטו שלא לשמו – such as when they were slaughtered for the sake of peace-offerings, or that the blood was received in the bowl out of which the sprinkling is done or brings the blood to the altar or he cast the blood on the altar.

או לשמו ושלא לשמו – such as that it was slaughtered for its sake but received the blood not for its sake.

או שלא לשמו – this ending part [of our Mishnah] teaches us that we consider from one form of Divine service to another, for if he thought at the time of the Divine service for this one on the service of its fellow [sacrifice] to perform with that thought, it is invalid, such when he said: “Behold I slaughter for its sake on the condition to cast its blood not for its sake, the sacrifice (i.e., festive peace-offering) is invalid immediately, and even if he didn’t perform the second as an invalid thought like the case as he thought, and that is the implication of our Mishnah, or that he thought at ther time of the slaughter to cast the blood not for its sake, we derive this from the Biblical verse, as it is written (Exodus 12:27): “You shall say, ‘It is the Passover sacrifice to the LORD’…” until it would be that the sacrifice is for the Passover offering and it implies to be indispensable.
