וְהוּכַ֣ח בְּ֭מַכְאוֹב עַל־מִשְׁכָּב֑וֹ וריב [וְר֖וֹב] עֲצָמָ֣יו אֵתָֽן׃
He is chastened also with pain upon his bed, And all his bones grow stiff;
Rashi on Job
And he is chastised an expression of reproof that he repent of his iniquity,
Rashi on Job
and most of his bones, which are strong, He chastises with pain.
