ציטירנדיקער פּירוש אויף בראשית 41:21

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.

ולא יודע השבע AND THE PLENTY SHALL NOT BE KNOWN — this is the interpretation of (v. 21) “And it could not be noticed that they had eaten them up”.
