Rashi on Genesis 29:14/רש"י על בראשית כ״ט:י״ד

1אך 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.
