• Kankanaey: “Then they asked-each-other saying, ‘What shall we answer? If we say that God is the one who gave his authority, Jesus will probably say, ‘If that is so, then why didn’t you believe/obey him?'” (Source: Kankanaey Back Translation)
• Tagbanwa: “When they heard that, they talked among themselves, ‘If we (incl.) say, ‘From God,’ he will then say to us, ‘Well why don’t you believe/obey him?'” (Source: Tagbanwa Back Translation)
