א֣וֹ נֶ֡פֶשׁ כִּ֣י תִשָּׁבַע֩ לְבַטֵּ֨א בִשְׂפָתַ֜יִם לְהָרַ֣ע ׀ א֣וֹ לְהֵיטִ֗יב לְ֠כֹל אֲשֶׁ֨ר יְבַטֵּ֧א הָאָדָ֛ם בִּשְׁבֻעָ֖ה וְנֶעְלַ֣ם מִמֶּ֑נּוּ וְהוּא־יָדַ֥ע וְאָשֵׁ֖ם לְאַחַ֥ת מֵאֵֽלֶּה׃
혹 누구든지 무심 중에 입으로 맹세를 발하여 악을 하리라 하든지 선을 하리라 하면 그 사람의 무심 중에 맹세를 발하여 말한 것이 어떠한 일이든지 깨닫지 못하다가 그것을 깨달을 때에는 그 중 하나에 허물이 있을 것이니
Bartenura
שבועות שתים – it is written in Scripture explicitly (Leviticus 5:4): “Or when a person utters an oath to bad or good purpose.” If he eats, it is for a good purpose; if he doesn’t eat, it is for a bad purpose, for he afflicts himself, and the same law applies for everything that is yes/positive or no/negative in the future, for to do bad or to do good in the future is implied.

שבועות שתים. שאוכל ושלא אוכל – these are the two which are explained, as it is written (Leviticus 5:4): “[Or when a man utters an oath] to bad or good purpose –[whatever a man may utter in an oath] that implies in the future, I will not eat for a bad purpose. I will eat for a good purpose.
Bartenura
נעלמה ממנו טומאה – and through that same act of forgetfulness/lack of awareness, he ate Holy Things, which is one [count], and he entered into the Sanctuary/Temple, which is two [counts], as it is written (Leviticus 5:4): “and the fact has escaped him,” and he is unclean/defiled, which implies that the defilement escaped him. But because he is not liable for it other than if he was aware at the beginning that he had become defiled/unclean and afterwards, it escaped him, because of this, it (i.e., the Mishnah) calls it: ידיעות הטמאה/awareness (plural) of uncleanness.
