Commentary for Genesis 31:43

מה אעשה לאלה WHAT CAN I DO UNTO THEM — How could it enter my mind injure them, my daughters!

AND TO MY DAUGHTERS, WHAT CAN I DO TO THESE TODAY? Commentators have said²³⁶Ibn Ezra and R’dak. that it is as if it were written, “And to my daughters, what could I do to them today?” and the word “them” constitutes additional clarification. Likewise, As we both of us have sworn,²³⁷I Samuel 20:42. [the word “we” serving as additional clarification]; We, our sons and our daughters,²³⁸Nehemiah 5:2. [the word “we” is here too mentioned for the greater clarity].
But it appears to be more correct that this is said in a compassionate way: “And to my daughters, what can I do to these who are before me, for I am deeply stirred for them, or unto their children, who have been born in my house, and they are to me as my children?” This is also the meaning of whom they have borne. Laban thus said this as if defending himself against Jacob’s words by claiming: “I have come after you to see my daughters, and to determine what favor I can do for them or their children. Now I can do them this good by seeing that you make me a covenant that you will not afflict them and will take no other wives in addition to them.”²³⁹Verse 50 here.

מה אעשה, how can I possibly harm them?
