39 The precise meaning of מְשֻׁלָּם (méshullam) in this context is uncertain. In later biblical Hebrew the form (which appears to be a Pual participle from the root שָׁלַם, shalam) occurs as a proper name, Meshullam. The Pual of שָׁלַם (“be complete”) is attested with the meaning “repaid, requited,” but that makes little sense here. 1023 שָׁלַם relates the form to the denominative verb שָׁלַם (“be at peace”) and paraphrases “one in a covenant of peace” (J. N. Oswalt suggests “the covenanted one”; Isaiah [], 2:, n. 59) Some emend the form to מֹשְׁלָם (moshélam, “their ruler”) or to מְשֻׁלָּחִי (méshullakhi, “my sent [or “commissioned”] one”), which fits nicely in the parallelism (note “my messenger” in the previous line). The translation above assumes an emendation to כְּמוֹ שֹׁלְמִי (kémo sholémi, “like my ally”). Isaiah uses כְּמוֹ in 30:22 and perhaps 51:5; for שֹׁלְמי (“my ally”) see Ps 7:5 (7:4 ).
40 Heb “Who is blind but my servant, and deaf like my messenger I send? Who is blind like my commissioned one, blind like the servant of the Lord?” The point of the rhetorical questions is that no one is as blind/deaf as this servant. In this context the Lord’s “servant” is exiled Israel (cf. 41:8–9), which is spiritually blind and deaf and has failed to fulfill God’s purpose for it. This servant stands in contrast to the ideal “Israel” of the servant songs.
