Genesis 41:22 Meaning

20And the lean and the ill favoured kine did eat up the first seven fat kine:

21And when they had eaten them up, it could not be known that they had eaten them; but they were still ill favoured, as at the beginning. So I awoke.

22And I saw in my dream, and, behold, seven ears came up in one stalk, full and good:

23And, behold, seven ears, withered, thin, and blasted with the east wind, sprung up after them:

24And the thin ears devoured the seven good ears: and I told this unto the magicians; but there was none that could declare it to me.
