Following are a number of back-translations as well as a sample translation for translators of Zechariah 2:9:

• Kupsabiny: “‘I shall fight with those communities and make those people who were their slaves to plunder their things.’ Then, you shall know that the God of authority is the one who sent me.” (Source: Kupsabiny Back Translation)
• Newari: “I will indeed lift up my hand against them. And their servants will plunder them."
  Because of this they will know that the LORD Almighty has sent me.” (Source: Newari Back Translation)
• Hiligaynon: “‘I will-punish them; they will-be-attacked by their slaves and will-take their possessions.’
  When this happens, then you (plur.) will-know that the LORD Almighty (is) the(-one-who) has-sent me.” (Source: Hiligaynon Back Translation)
• English: “it is as though I will strike them with my fist, with the result that those who were their slaves will now take back their possessions from those who caused them to become slaves.’ And when that happens, you will know that the Commander of the armies of angels is the one who sent me.’” (Source: Translation for Translators)
