Parallel
Numbers 31:19
Berean Standard Bible · Westminster Leningrad Codex
All of you who have killed a person or touched the dead are to remain outside the camp for seven days. On the third day and the seventh day you are to purify both yourselves and your captives.
וְאַתֶּ֗ם חֲנ֛וּ מִח֥וּץ לַֽמַּחֲנֶ֖ה שִׁבְעַ֣ת יָמִ֑ים כֹּל֩ הֹרֵ֨ג נֶ֜פֶשׁ וְכֹ֣ל׀ נֹגֵ֣עַ בֶּֽחָלָ֗ל תִּֽתְחַטְּא֞וּ בַּיּ֤וֹם הַשְּׁלִישִׁי֙ וּבַיּ֣וֹם הַשְּׁבִיעִ֔י אַתֶּ֖ם וּשְׁבִיכֶֽם׃
