בְּיַד־כָּל־אָדָ֥ם יַחְתּ֑וֹם לָ֝דַ֗עַת כָּל־אַנְשֵׁ֥י מַעֲשֵֽׂהוּ׃
ער פֿאַרחתמעט די האַנט פֿון יעטװעדער מענטשן, אַז אַלע מענטשן פֿון זײַן באַשאַף זאָלן װיסן.
Rashi
By the hand of every man he seals When a man sins before Him, the man himself signs his signature on the day of his death to the sins that he committed, which are written before him.
Rashi
so that every man should know his deed to let him know for what he is being judged.
