וְאַתָּ֨ה בֶן־אָדָ֜ם קַח־לְךָ֣ ׀ חֶ֣רֶב חַדָּ֗ה תַּ֤עַר הַגַּלָּבִים֙ תִּקָּחֶ֣נָּה לָּ֔ךְ וְהַעֲבַרְתָּ֥ עַל־רֹאשְׁךָ֖ וְעַל־זְקָנֶ֑ךָ וְלָקַחְתָּ֥ לְךָ֛ מֹאזְנֵ֥י מִשְׁקָ֖ל וְחִלַּקְתָּֽם׃
And thou, son of man, take thee a sharp sword, as a barber’s razor shalt thou take it unto thee, and cause it to pass upon thy head and upon thy beard; then take thee balances to weigh, and divide the hair.
