Following are a number of back-translations of Acts 3:18:

• Western Bukidnon Manobo: “Long ago, God by means of the prophecies of those whom he inspired, caused to understand that the king whom he chose would be tortured by people. And he caused this to come to pass by means of what you did.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “But the death of Jesus, that was the fulfillment of what God caused-to-be-written long-ago, because all the prophets, they said that the Messiah that he would send had to suffer and die.” (Source: Kankanaey Back Translation)
