43 Heb “the days of the Baals, to whom she burned incense.” The word “festival” is supplied to clarify the referent of “days,” and the word “idols” is supplied in light of the plural “Baals” (cf. “her images of Baal”).
44 The vav prefixed to a nonverb (וְאֹתִי, vé’oti) introduces a disjunctive contrastive clause, which is rhetorically powerful.
45 The accusative direct object pronoun וְאֹתִי (vé’oti, “me”) is emphatic in the word order of this clause (cf. “but me she forgot”), emphasizing the heinous inappropriateness of Israel’s departure from the Lord.
