Concern for a mishap
אולי ימשני אבי והייתי בעיניו במתעתע והבאתי עלי קללה ולא ברכה: ותאמר לו אמו עלי קללתך בני שמע בקלי ולך קח-לי
Maybe my father will feel me and I will seem like a deceiver in his eyes, and he will bring upon me a curse and not a blessing. His mother said to him: “Your curse [will be] upon me my son. Listen to my voice, go and take [what I told you to]
The climax of this week’s parsha contains Rivka’s dramatic plot to secure blessings for her son Yaakov, preventing her other son Eisav from receiving them. The blind Yitzchak decided Eisav was more worthy of his final blessings, and requested his talented son go and hunt him some game. While Eisav was away, Yaakov was to enter Yitzchak’s tent, pretend to be Eisav, and receive the blessings himself. Yaakov was reluctant at first, explaining to his mother that the plan was dangerous. Eisav was a very hairy man, and Yaakov was smooth-skinned. What if Yitzchak would feel Yaakov’s arms and realize that he’s not really Eisav? Yitzchak would label Yaakov a deceiver. He would receive his father’s curses, not blessings! His mother reassured him, that no curse would befall him.
