E as sete vacas magras e ruins que vêm depois delas são sete anos, e as sete espigas vazias, queimadas pelo vento leste, serão sete anos de fome.
Rabbeinu Chananel
The reason why we have two verses in both of which G’d is reported as speaking (separately) although no mention is made of Avram making any response in between, is that the first verse commencing with ויאמר was not a verbalised version of what G’d “said,” but describes what he thought. Such constructions are not unique, other examples occurring in Genesis 27,41 ויאמר עשו בלבו, “Esau said in his heart, etc.” It is reported as Esau having said something, else how could his mother have heard it? Solomon, in Kohelet 2,1 also uses the word אמרתי when describing something he thought rather than something he had actually said.
Rashi
neither shall it be inhabited for forty years Forty-two years of famine were decreed in Pharaoh’s dream, corresponding to the three times the dream is written. He saw seven bad cows and seven bad ears of grain (Gen. 41) and he told it to Joseph; hence we have [it mentioned] twice, and Joseph said to him, “The seven thin and bad cows and the seven empty ears,” totaling forty-two for the famine. But they had only two, as it is stated (ibid. 45:6): “For it is two years now that the famine has been on earth,” and when Jacob came down to Egypt, the famine ceased, for behold in the third year they sowed, as it is stated (ibid. 47:19): “and then you give us seed that we may live etc.,” and the forty years were paid to them now: “neither shall it be inhabited for forty years.”
Chizkuni
ודישון ואצר ודשן, as well as Dishon, Atzar, and Dishan.” According to the vocalisation by the authors of the tradition that we rely on, the sequence for reading these names is as follows: דישון, דישן, דישון, דישן, דישן דישון, דישן to help us memorize this sequence (these names appear a total of seven times) it pays to commence with the seventh day, i.e. Shabbat. On the seventh day the second day and the fifth day of the week (the three days of the week the Torah is read in public) this recalls the spelling with the letter ו. On the days of the week when we do not read from the Torah in public, i.e. first, third, fourth and sixth day, this recalls the times it is read as if spelled defectively. Do not be astounded concerning the phrasing of: ואלה בני דישן חמדן וגו', “and these were the sons of Dishon, Chemdon,” in verse 27. This refers to the first time we read about דישון. Verse 27 refers back to דישן in verse 26 which should have been vocalised as דישון. We must understand that whenever in the Holy Scriptures books written later, refer to names of persons or places which appear spelled differently from the first time they had appeared, they refer to the ones mentioned the first time in the Bible, unless otherwise stated. Examples of the names of the same people, or the same verbs, being spelled differently in different Books of the Bible, are: Samuel II 22 as opposed to Psalms chapter 18, where the word מגדל, in verse 51 of the former means the same as the word מגדיל in the verse 51 of Psalms.[You will note the similarity of the subject matter in both chapters, plus the fact that both of these words appear in verse 51 of the chapter mentioned. Compare also Genesis 32,32 and 31 respectively, where the name of the place פנואל is once spelled with the letter ו and the other time with the letter י in the middle. Compare the spelling of the ears of corn in Pharaoh’s dream in Genesis 41,7 as דקות, and when Joseph interprets it in about it in Genesis 41,27, as רקות. Our author cites a few more examples which I have decided to skip as he has made his point. Ed.]
