Now there was a famine in the land, and Abram went down to Egypt to live there for a while because the famine was severe.
Genesis 12:10 (NIV)The seven years of abundance in Egypt came to an end, and the seven years of famine began, just as Joseph had said. There was famine in all the other lands, but in the whole land of Egypt there was food.
Genesis 41:53-54 (NIV)
Earlier, I mentioned Genesis 12 is an echo of Genesis 1.
But the great Famine at the end of Genesis, leading to the deliverance in Exodus is an echo of Genesis 12.
All of scripture echoes. Every last bit of it.
