Shevuos 1:2 - 1:3

שיש בה ידיעה בתחלה – this refers to awareness of uncleanness, for since small/trifle things are explained in the opening clause [of the Mishnah] and it goes back and explains oaths which are large mattes, and the transporting [of objects on the Sabbath] and appearances [of plagues] , each and every one is explained in its own tractate, therefore, he (i.e., the Tanna) does not explain them in this Tractate, and they are not taught here other than because they are similar to each other in two sorets which yield four subdivisions.

וידיעה בתחלה – that he knew that he became defiled.

וידיעה בסוף – from when he ate the Holy thing in an act of forgetfulness/that it escaped him, or entered into the Sanctuary in act of forgetfulness/that it escaped him and he left, and it became known to him that in defilement he ate or that in defilement he entered [into the Sanctuary].

ןהעלם בינתיים– when he ate the Holy food, the defilement or the sanctity [of the place] in act of forgetfulness/that it escaped him or he entered into the Sanctuary and in an act of forgetfulness/that it escaped him, the defilement or the Sanctuary.

הרי זה בעולה ויורד – a burnt offering for a wealthy individual and something of lesser value for a poor person. The wealthy person brings a sin-offering of cattle, and a poor person the sin offering of fowl, and the poorest of he poor, one tenth of an Ephah, which is a meal offering of sinner that is mentioned in every place.

שעיר הנעשה בפנים – the goat of Yom Kippur that he brings from its blood inside.

תולה – to protect him from suffering/trials.

עד שיודע לו – that he ate Holy things in a state of ritual impurity, and he brings the Sacrifice of Higher or -11; Tractate Shevuot 21a).

אין בה ידיעה בתחלה – he did not know about this ritual defilement at all, this does not into the category of [a required] sacrifice ever, for the sacrifice dos not come other than when he has awareness [of ritual impurity] at the beginning.

שעיר הנעשה בחוץ – that is offered on the outer altar [which yields blood to be sprinkled] during the Musaf of Yom Kippur.

ויום הכיפורים – itself atones with the goat.

שנאמר – regarding the goat that is offered on the outer altar (Numbers 29:11): “And there shall be one goat for a sin offering, in addition to the sin offering of expiation,” for the sin offering of expiation is the goat that is offered inside and Scripture juxtaposed them, to teach you just as one expiates/atones, so too the other atones/expiates; the inside [goat] doesn’t come other than with a matter about which there is awareness, and what is this awareness? At the outset, as we derive from Scripture, as it is written (Leviticus 16:21): “[Aaron shall lay both his hands upon the head of the live goat and confess over all the iniquities and transgressions of the Israelites,] whatever their sins, [putting them on the head of the goat],” which implies that for those that come within the category of sin - , that they should have awareness of them at the conclusion, and it is impossible that to come within the category of sin-offering other than if they had awareness at the outset, even the goat that is offered outside does not atone other than if he as awareness of it, and what is it? Awareness at the conclusion and not at the beginning, for they are not included in the category of sacrifice, and this atoning is complete atonement/expiation without doubt.
