א֣וֹ כִ֤י יִגַּע֙ בְּטֻמְאַ֣ת אָדָ֔ם לְכֹל֙ טֻמְאָת֔וֹ אֲשֶׁ֥ר יִטְמָ֖א בָּ֑הּ וְנֶעְלַ֣ם מִמֶּ֔נּוּ וְה֥וּא יָדַ֖ע וְאָשֵֽׁם׃
혹시 부지 중에 사람의 부정에 다닥쳤는데 그 사람의 부정이 어떠한 부정이든지 그것을 깨달을 때에는 허물이 있을 것이요

Where there is knowledge at the beginning and at the end but forgetfulness between, a “sliding scales” sacrifice is brought. Where there is knowledge at the beginning but not at the end, the goat which is [sacrificed and its blood sprinkled] within [the Holy of Holies on the Day of Atonement] together with the Day of Atonement itself hold the sin in suspense until it become known to the sinner, and he brings the “sliding scale” sacrifice.
Mishnah Shevuot
Rabbi Eliezer said: “[Scripture says: ‘If any one touch… the carcass of] an impure creeping thing, and it be unknown to him’ (Leviticus 5:2), when the impure creeping thing is unknown to him, he is liable; but he is not liable, when the [fact that he is in the] Temple is unknown to him.” Rabbi Akiba said: “[Scripture says:] ‘and it be hidden from him that he is impure’: when his impurity is unknown to him, he is liable; but he is not liable, when the [fact that he is in the] Temple is unknown to him.” Rabbi Ishmael said: “[Scripture] twice [says:] ‘and it be hidden from him’, in order to make him liable both for the forgetfulness of the impurity and the forgetfulness of the Temple.”
