וַיֹּ֤אמֶר לוֹ֙ לָבָ֔ן אַ֛ךְ עַצְמִ֥י וּבְשָׂרִ֖י אָ֑תָּה וַיֵּ֥שֶׁב עִמּ֖וֹ חֹ֥דֶשׁ יָמִֽים׃
라반이 가로되 너는 참으로 나의 골육이로다 하였더라 야곱이 한달을 그와 함께 거하더니
Rashi on Genesis
אך עצמי ובשרי SURELY THOU ART MY BONE AND MY FLESH — Really, I have no reason to take you into my house, since you have brought nothing with you; but because of our relationship I will put up with you for “the space of a month”. Thus, indeed, he did, but even this was not for nothing, for he tended Laban’s sheep.
Rashbam on Genesis
אך עצמי ובשרי, you have therefore done well in coming to me.
Sforno on Genesis
אך עצמי ובשרי אתה, even though you are no doubt able to make a living without me by undertaking to look after the flocks or in some other manner, the fact remains that you are my flesh and blood and it is therefore appropriate that you should stay under my roof.
