I odpowiedzieli Laban i Betuel i rzekli: "od Wiekuistego wyszła ta rzecz; nie możemy ci powiedzieć ani źle, ani dobrze.
Rashi on Genesis
ויען לבן ובתואל THEN LABAN AND BETHUEL ANSWERED —He (Laban) was a wicked person and so rushed in to answer before his father.
Rashbam on Genesis
לא נוכל דבר אליך רע או טוב, the success or failure of His plan is not up to us to either confirm or thwart. This has been fated by G’d regardless of whether we like it or not. G’d will accomplish His will as He has the power to bring this about.
Sforno on Genesis
לא נוכל דבר אליך רע, in order to neutralise His decree.
