משנה: הָיָה עוֹמֵד בִּתְפִילָּה וְנִזְכַּר שֶׁהוּא בַּעַל קֶרִי לֹא יַפְסִיק אֶלָּא יְקַצֵּר. יָרַד לִטְבּוֹל אִם יָכוֹל לַעֲלוֹת וּלְהִתְכַּסּוֹת וְלִקְרוֹת עַד שֶׁלֹּא תֵנֵץ הַחַמָּה יַעֲלֶה וְיִתְכַּסֶּה וְיִקְרָא וְאִם לָאו יִתְכַּסֶּה בַמַּיִם וְיִקְרָא. לֹא יִתְכַּסֶּה לֹא בַמַּיִם הָרָעִים וְלֹא בְמֵי הַמִּשְׁרָה עַד שֶׁיַּטִּיל לְתוֹכָן מַיִם. וְכַמָּה יִרְחִיק מֵהֶן וּמִן הַצּוֹאָה אַרְבַּע אַמּוֹת.
MISHNAH: If someone was standing and praying when he remembered that he had qeri, he should not stop but shorten his prayer. If he descended to immerse himself, if he can ascend, get dressed, and recite by the time of sunrise he should ascend, get dressed, and recite; otherwise, he should cover himself with water and recite. He should cover himself neither with stinking water nor with steeping water unless he diluted them with water. How much does one have to remove oneself from these and excrement? Four cubits.
