Bereishit (24:24), “And she said to him, the daughter of Betuel אנכי (I am) the son of Milka….” אנכי is out of place. Rivka was saying that although she was the daughter of Betuel, she was still אנכי, her own person. Bereishit (25:22), “And the children agitated within her, and she said, if so, למה זה אנכי.” Rivka was saying, if I will have a wicked child, why did I strive to be אנכי, my own person.
