tnHeb “hostile ones of Judah.” Elsewhere when the substantival participle of צָרָר (tsarar) takes a pronominal suffix or appears in a construct relationship, the following genitive is objective. (For a list of texts see BDB 865s.v. III צָרַר) In this case the phrase “hostile ones of Judah” means “those who are hostile toward Judah,” i.e., Judah’s enemies. However, the parallel couplet that follows suggests that Judah’s hostility toward Ephraim is in view. In this case “hostile ones of Judah” means “hostile ones from Judah.” The translation above assumes the latter, giving the immediate context priority over general usage.
