Following are a number of back-translations of John 16:30:

• Uma: “It is very clear to us (excl.): the Lord is the one who knows all. It is no longer necessary that anyone ask you (sing.) anything. That is why we (excl.) believe that you (sing.) are from God.'” (Source: Uma Back Translation)
• Yakan: “Now we (excl.) are sure that you know everything even though nobody asks you. Therefore we (excl.) really believe that you are from God.'” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “We know that you know everything because we don’t even have to ask you questions because you know about them already. That’s why we believe that you come from God.'” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “Now indeed, we (excl.) surely know that you (sing.) know everything. Even the questions that are in a person’s mind, they don’t need to be told to you (sing.), because you (sing.) already know. Therefore we (excl.) believe that you (sing.) came-from God.'” (Source: Kankanaey Back Translation)
• Tagbanwa: “Now we (excl.) know that you are aware of all things. You don’t need to be questioned by anyone so that you will know what is in his mind/thinking, because even if he hasn’t yet brought-to-the-surface what he wants to ask about, you already know. Therein we (excl.) believe now that really as for you, you have truly come from God.'” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “Now we understand that you know everything. It isn’t necessary that first someone questions you. So we believe that you came from heaven where God is.'” (Source: Tenango Otomi Back Translation)
