Following are a number of back-translations of Matthew 5:34:

• Uma: “But I say: don’t swear/make vows at all. If we (incl.) make a promise, don’t swear naming the sky or earth. Because the sky is the sitting-place of God and the earth is his stepping-place. Don’t swear naming the city of Yerusalem, because that is the city of God the big King.” (Source: Uma Back Translation)
• Yakan: “But I, I say: if you promise anything do not swear calling on (lit. uttering) heaven, because there is the sitting place of God. Do not swear calling on the earth because this is the resting place of God’s feet. Do not swear calling on the city of Awrusalam because this is the city ruled/held by the Most Powerful King.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “And I say to you, if there is that which you promise to anyone, don’t you swear saying that may heaven and earth where you stand collapse if what you say isn’t true, because heaven is where God sits and the earth is where his feet rest. And don’t you also say that may the town of Jerusalem be destroyed if what you say isn’t true, because that’s where the great king will live.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “But I say to you that you are absolutely not to swear. Do not say, ‘Look you (sing.) heaven,’ (an expression used to call God, etc. as witness) because that is where-God -sits to rule.” (Source: Kankanaey Back Translation)
• Tagbanwa: “But now/today I am the one saying to you that you no longer make vows. Don’t say any more, ‘Heaven is my witness,’ for this heaven is like God’s seat in kingship.” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “But I tell you that you must not call upon God as a witness when you speak in order to reinforce your words. And concerning what is in heaven, do not call upon it for a witness, because there it is that God lives, it is as though you called upon him as a witness.” (Source: Tenango Otomi Back Translation)
