Following are a number of back-translations as well as a sample translation for translators of Genesis 27:33:

• Newari: “Hearing this Isaac trembled violently. Then he said — ‘If so, who was it that hunted and fed me meat before you came? I have already given him the blessing. [And] he will now indeed be blessed.'” (Source: Newari Back Translation)
• Hiligaynon: “When Isaac heard this, he trembled-violently and said, ‘Who was [surprise particle] the-one-who hunted and brought food here to me? I had- just recently -eaten it and then you (sing.) arrived. I already gave to him my blessing and I can- not [emphasis] -retrieve it.'” (Source: Hiligaynon Back Translation)
• English: “Then Isaac, realizing that it was not Esau who had come earlier, trembled very violently. He said, ‘Then who is it that brought me some meat from an animal that he had hunted and killed, and I ate it all? He was here just before you came. I blessed him, and I cannot take back that blessing/declare that those things will not happen to him.'” (Source: Translation for Translators)
