Following are a number of back-translations of Romans 4:3:

• Uma: «For there is something written in the Holy Book that speaks of Abraham like this: ‘Abraham believed God, and because of his faith God said he was straight in his sight.'» (Source: Uma Back Translation)
• Yakan: «What does the holy-book say about Ibrahim? The holy-book says that Ibrahim believed God’s promise to him. And because of that belief of his he was forgiven and he was considered straight by God.» (Source: Yakan Back Translation)
• Western Bukidnon Manobo: «The reason we know this is because there is a written word of God which says, ‘Abraham believed in God, and because of this belief of His, God considered him to be righteous.'» (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: «Because there is a written word of God which says, ‘Abraham believed/obeyed what God said, so God counted him as righteous.'» (Source: Kankanaey Back Translation)
• Tenango Otomi: «It says in the Holy Book how it is that God cleared Abraham. It says: ‘Abraham believed that the word God said would happen. In that he believed, for that God cleared him.'» (Source: Tenango Otomi Back Translation)
• Chichewa (interconfessional translation, 1999): «Thus what do the Writings say? They say, ‘Abraham believed God, and upon that believing, God viewed him as [being] righteous.'» (Source: Wendland 1998, p. 112)
