41 Heb “The great day of the Lord.” The words “of judgment” are supplied in the translation here and later in this verse for clarity. See the note on the expression “day of judgment” in v. .
42 Heb “the sound of the day of the Lord, bitter [is] one crying out there, a warrior.” The present translation does four things: (1) It takes מַר (mar, “bitter”) with what precedes (contrary to the accentuation of the ). (2) It understands the participle צָרַח (tsarakh, “cry out in battle”) as verbal with “warrior” as its subject. (3) It takes שָׁם (sham, “there”) in a temporal sense, meaning “then, at that time.” (4) It understands “warrior” as collective.
43 Heb “a day of wrath.” The word “God’s” is supplied in the translation for clarification.
44 Heb “a ram’s horn.” By metonymy the Hebrew text mentions the trumpet (“ram’s horn”) in place of the sound it produces (“trumpet blasts”).
45 This description of the day of the Lord consists of an initial reference to anger, followed by four pairs of synonyms. The joining of synonyms in this way emphasizes the degree of the characteristic being described. The first two pairs focus on the distress and ruin that judgment will bring; the second two pairs picture this day of judgment as being very dark (darkness) and exceedingly overcast (gloom). The description concludes with the pairing of two familiar battle sounds, the blast on the ram’s horn (trumpet blasts) and the war cries of the warriors (battle cries).
46 Heb “against.” The words “judgment will fall” are supplied in the translation for clarification.
