The voice is the voice of Jacob, but the hands are the hands of Esau
The matter appears to be something that is not truly so. A wonder at the existing contradiction in a certain thing that appears in one form but its meaning is different. A term for suspicion, for lack of trust (the recipient's likeness from the words of Isaac when he heard Jacob approaching him dressed in Esau's garments).
("And Jacob went near to Isaac his father, and felt him, and said, The voice is Jacob's voice, and the hands are the hands of Esau" - Genesis 27:22, and likewise: "The voice is Jacob's voice, and the hands are the hands of Esau," as long as Jacob's voice is found in synagogues and in the houses of study, the hands are not the hands of Esau. And if not, "The hands are the hands of Esau," you (the nations of the world) can have them" - Genesis 27:7)
