Following are a number of back-translations as well as a sample translation for translators of Zechariah 9:7:

• Kupsabiny: “I will make them no longer eat food that is not clean and make their remnant bow to me like those of the house of Judah. The people of Ekron will be like the Jebusites.” (Source: Kupsabiny Back Translation)
• Newari: “I will take from their mouths meat with blood still in it
  and I will take abominations from between their teeth.
  Then the surviving Philistines will be God’s people
  and it shall be like a clan in Judah.
  The ones living in Ekron will be like the Jebusites.” (Source: Newari Back Translation)
• Hiligaynon: “They will- no longer/[lit. not now] -eat meat with blood or the food that (are) forbidden to eat. Those who (are) left among them God will-consider (them) as his people, as-if-like a group of people (who belong) to Juda. The residents of Ekron will-be part of the people of the LORD like the Jebusnon.” (Source: Hiligaynon Back Translation)
• English: “I will no longer allow them to eat meat that still has blood in it,
  and I will forbid them to eat food that I have not allowed them to eat because it was offered to idols.
  At that time, the people in Philistia who survive will worship me,
  and they will become my people, like the people of Judah are.
  The Philistine people of Ekron will also become my people
  like the people of Jebus did when they were conquered.” (Source: Translation for Translators)
