Sforno on Genesis 41:19/ספורנו על בראשית מ״א:י״ט

1לא ראיתי כהנה, Pharaoh meant that such a dream as he had did not reflect anything that he might have thought about during the preceding day, as is usual for most dreams. For what he had seen in his dream was beyond anything he had ever experienced while awake. (compare Daniel 2,29). [the novelty of Seforno’s approach is that he does not understand the word כהנה as referring merely to the frightening appearance of the lean cows. Ed.]
