Following are a number of back-translations of Matthew 5:33:

• Uma: “‘You also know that there is a command that was said to our (incl.) ancestors long ago that says: ‘Don’t retreat from your (sing.) promise or your (sing.) vow. What you (sing.) promised in front of God, you (sing.) must definitely do.'” (Source: Uma Back Translation)
• Yakan: “‘You have also heard about the teaching of the people of old, it says, ‘Do not swear if it is not true. And you shall fulfill it if you promise something before God (lit. in the hearing of God).'” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “You know also that which was taught long ago to our ancestors that if there is that which you promised to the Lord, it not possible that you do not fulfill it. You must fulfill it.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “Jesus continued saying, ‘You have also heard what was commanded to our ancestors in the distant-past that it is necessary that they not break (as a law) what they have-sworn, but rather that they fulfill what they have sworn to the Lord God.” (Source: Kankanaey Back Translation)
• Tagbanwa: “‘You (pl.) have also indeed heard that law of the past which says, ‘Don’t ignore/fail-to-act-on your (sing.) promise which you vowed, but on the contrary really fulfill what you promised to God.'” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “You have heard the word taught to the old-time people in past days, that they were told: ‘ When you call upon God as a witness that you will truly do what you say, then it is very necessary that you do the word which you have promised to do.'” (Source: Tenango Otomi Back Translation)
