Following are a number of back-translations of Acts 8:31:

• Yakan: «The official answered, ‘How can I understand if no one explains it to me?’ And he told Pilip to ride and sit beside him.» (Source: Yakan Back Translation)
• Western Bukidnon Manobo: «And the official said, ‘How can I understand this when there is no one to interpret for me?’ And he caused Philip to ride.» (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: «‘No, because there is no one to explain it to me,’ he said in reply. Then he invited Felipe to ride-with-(him).» (Source: Kankanaey Back Translation)
• Tagbanwa: «‘I don’t understand anything,’ was the reply of that taga Etiope. ‘Maybe if there was someone to explain to me, I would understand it.’ Therefore he then caused Felipe to ride.» (Source: Tagbanwa Back Translation)
