This article proposes that Zech 6,5 mhtxb al-adin cl-harez indicates that the heavenly chariots are sent forth in response to rebellion against the Lord. It argues that mn plus the infinitive has a causal force and that htxb al means 'to take a stand (in opposition or rebellion)' (cf. Ps 2,2) rather than 'to present oneself'. This rebellion is the antecedent of the pronominal suffix in v. 6's asr-bt, indicating the object against which the chariotry is going forth. Rather than being the narrative of a peaceful patrol, the vision indicates that God's emissaries are engaged in warfare.
