Y entró también á Rachêl: y amóla también más que á Lea: y sirvió con él aún otros siete años.
Siftei Chakhamim
More than is. . . The מ [of מדי ] means “more than,” as in (Bereishis 29:30), “He loved Rochel more than Leah ( מלאה ).” Rashi adds the phrase, “What was needed for,” because the people brought only what was needed for the work, not the [completed] work itself.
Rashbam
גם השתרר, the word גם in the Torah appears quite often as an introduction to something opposite or totally different from what had preceded it. Our verse is an example of such use, the line כי תשתרר ילינו גם השתרר meaning “do you now also want to lord it over us?” Another such example is found in Exodus 12,32 where Pharaoh begs Moses to bless him, using the word גם, although this word in that context certainly is not a continuation of any previously discussed thought. Genesis 29,30 as well as Numbers 22,33 where the angel said to Bileam גם הרגתי אותך “I would also have killed you,” is totally out of keeping with the standard meaning of the word גם when it is translated as “also.” [the angel had not killed the ass as yet. Ed.]
Ramban
WHEN SHALL I PROVIDE ‘GAM’ (ALSO) FOR MINE OWN HOUSE? “At present, my sons alone provide for my needs, but I also ought to work together with them and assist them.” This is the force of the word gam (also). These are Rashi’s words. But we do not find that Jacob had his own sheep, nor do we find mentioned anywhere that his young children — the oldest of whom was six years or less — tended them. It was possible that before Jacob came, Laban had children younger than Rachel156This is a reference to what Rashi explained in Verse 27 that since Jacob’s arrival, a blessing came upon Laban and he begot sons, “for is it possible that if he previously had sons, he would have let his daughter Rachel go among the shepherds?” Yet he had sons, as it is said, And he [Jacob] heard the words of Laban’s sons, (further, 31:1). We must say that these sons were born to him after Jacob came. and now they were fit to tend the flock. [However, Jacob’s children were still very young.] Perhaps Jacob referred to his wives and servants, who he said did his work for him. But all this is not correct. The meaning of, When shall I provide also for mine house? is: “When shall I provide for my house just as I have also done for your house.” Similarly, And he loved also Rachel from Leah,157Above, 29:30. means “And he loved Rachel also more than he loved Leah.” And similarly, Also thee I would have slain,158Numbers 22:33. means “Also I would have slain thee.” And there are many other such verses.
