וַתָּבֹ֣אנָה אֶל־קִרְבֶּ֗נָה וְלֹ֤א נוֹדַע֙ כִּי־בָ֣אוּ אֶל־קִרְבֶּ֔נָה וּמַרְאֵיהֶ֣ן רַ֔ע כַּאֲשֶׁ֖ר בַּתְּחִלָּ֑ה וָאִיקָֽץ׃
Celles ci donc passèrent dans leur corps, mais on ne se serait pas douté qu’elles y eussent passé: elles étaient chétives comme auparavant. Je m’éveillai.
Ramban
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.
Rashi
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”.
