Following are a number of back-translations of Matthew 21:31:

• Uma: «From there, Yesus asked the Yahudi religion leaders, he said: ‘So, of those two children, who followed the commands of their father?’ The Yahudi leaders said: ‘The first.’ Yesus said: ‘Truly I say to you: sinners like tax collectors and women whose behavior is not appropriate, it is they whom God will receive to be his people/subjects in his Kingdom, not you.» (Source: Uma Back Translation)
• Yakan: «Then Isa said, ‘Which of them did the will of his father?’ They said, ‘The older one.’ So-then Isa said to them, ‘Truly I tell you, the sinful people like the tax collectors and the bad women, God will receive them before you.» (Source: Yakan Back Translation)
• Western Bukidnon Manobo: «Then said Jesus, ‘Who of these two is the one who obeyed their father’s command?’ And they said to Jesus, ‘It was the older.’ And Jesus said again, ‘The bad people like the tax collectors and the women who make money through their reputation, they are ahead of you, because God will accept them that he might rule them, not you.» (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: «OK then,’ said Jesus, ‘which of these two fulfilled what their father wanted?’ ‘The older-brother of course,’ they said. ‘Right,’ said Jesus, ‘and this that I tell you is true that the characteristically-sinful people like the tax collectors and the prostitutes (lit. women whose womanhood can be bought), they will go-ahead of you to be added to God’s ruling.» (Source: Kankanaey Back Translation)
• Tagbanwa: «Well which of those two followed/obeyed the will of their father?’ ‘That older one,’ was their answer to Jesus. ‘What I will say to you is really true,’ said Jesus next, ‘that the money-grabbing official-receivers of payment and the women who make money with their bodies will go ahead of you in being able to become subjects of the kingdom of God.» (Source: Tagbanwa Back Translation)
• Tenango Otomi: «So now, which of the two sons did what his father ordered?’ The people answered and said: ‘It is the son who was first told that did what his father ordered.’ Again Jesus said to them: ‘Truly I tell you, that the tax collectors and the women who are prostitutes enter the hand of God before you do.» (Source: Tenango Otomi Back Translation)
