The repetition of a thing serves to confirm it. How sweetly do we find it to be so, respecting eternal things. Hebrews 6:17-18.
Genesis 41:18-25
18 And, behold, there came up out of the river seven kine, fatfleshed and well favoured; and they fed in a meadow:
19 And, behold, seven other kine came up after them, poor and very ill favoured and leanfleshed, such as I never saw in all the land of Egypt for badness:
20 And the lean and the ill favoured kine did eat up the first seven fat kine:
21 And 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.
22 And I saw in my dream, and, behold, seven ears came up in one stalk, full and good:
23 And, behold, seven ears, withered,b thin, and blasted with the east wind, sprung up after them:
24 And 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.
25 And Joseph said unto Pharaoh, The dream of Pharaoh is one: God hath shewed Pharaoh what he is about to do.
