Following are a number of back-translations of Acts 7:51:

• Uma: “Stefanus also said to the Yahudi elders: ‘No kidding the hardness of your wisdom teeth, relatives! No kidding your stubbornness! No kidding your making yourselves deaf to hearing the Word of the Lord God! You are definitely the same as our ancestors long ago, continually rejecting the Holy Spirit.” (Source: Uma Back Translation)
• Yakan: “Then Estepan said to the councilors and to the people, ‘How hard your heads are. Your livers are livers not obeying/following God. And how deaf are your ears. You do not listen-to/heed God’s word/message. You are just like your forefathers long-ago. You also do not listen-to/heed the Holy Spirit.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “Now,’ said Stephen, ‘you my companion Jews, your breath is very hard. You do not want to listen to and you do not want to obey the word of God. You never stop transgressing against the Holy Spirit. That which our ancestors did is also what you do.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “Then he continued saying, ‘Your mind/thoughts are hard/stubborn. You are like pagans who refuse to believe in God and turn-a-deaf-ear-to what he says. You also take-after the way our ancestors continually opposed the Holy Spirit.” (Source: Kankanaey Back Translation)
• Tagbanwa: “Well now,’ said Esteban, ‘I will speak plainly. For your heads are so hard! And as for your ways/nature, it’s really just like the people who have no knowledge of God, for you just refuse-to-listen to his word. You are always opposing the Espiritu Santo, just like your ancestors did.” (Source: Tagbanwa Back Translation)
