פּירוש אויף בראשית 41:3

ודקות בשר THIN-FLESHED in old French tenuis, meaning thin.

שבע פרות, “seven cows;” an allusion to the seven years of plenty and the seven years of famine to occur. Cows are relevant animals as they do the ploughing in order for crops to grow.

AND THEY STOOD BESIDE THE COWS. I.e., by their side and near them. This was a sign that there would be no lapse of time between the years of plenty and the years of famine even though Pharaoh did not relate this to Joseph.²³See Verse 19 here. But perhaps the vision which Pharaoh saw and the relating of the dream to Joseph were really alike, except that Scripture did not concern itself [with mentioning all the details Pharaoh told Joseph], just as it added into the story [details not mentioned in the actual dream, as for example], And it could not be known that they had eaten them up,²⁴Verse 21 here. and also, the ears of corn came up on one stalk,²⁵Verse 5 here. which was a sign that the seven years will occur consecutively.
