49 Heb “his ways” (so , , ); “how they acted.”
50 Heb “and I will restore consolation to him, to his mourners.”
51 The Hebrew text has literally, “one who creates fruit of lips.” Perhaps the pronoun אֲנִי (’ani) should be inserted after the participle; it may have been accidentally omitted by haplography: נוּב שְׂפָתָיִם[אֲנִי] בּוֹרֵא (bore’ [’ani] nuv séfatayim). “Fruit of the lips” is often understood as a metonymy for praise; perhaps it refers more generally to joyful shouts (see v. 18).
52 Heb “Peace, peace.” The repetition of the noun emphasizes degree.
