כִּ֠י אִֽם־אֶל־הַמָּק֞וֹם אֲשֶׁר־יִבְחַ֨ר יְהוָ֤ה אֱלֹֽהֵיכֶם֙ מִכָּל־שִׁבְטֵיכֶ֔ם לָשׂ֥וּם אֶת־שְׁמ֖וֹ שָׁ֑ם לְשִׁכְנ֥וֹ תִדְרְשׁ֖וּ וּבָ֥אתָ שָֽׁמָּה׃
唯有永恆者你們的上帝從你們各支派中所選擇、要在那裡立祂名的地方，就是祂的居所，你們要去尋求，你也要往那裡去。
Tosefta Chagigah
One who is impure is exempt from appearing [before the Temple on the three festivals], as it says (Deut. 12:5-6), "you are to come there and you are to bring there [your burnt-offerings and your sacrifices]." Since one must be [ritually] fit to enter the Temple Courtyard, consequently one who is impure, who is not fit to enter the Temple Courtyard[, is exempt from appearing].
