Genesis 43:1

And the LORD said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old?

And the seven years of dearth began to come, according as Joseph had said: and the dearth was in all lands; but in all the land of Egypt there was bread. And when all the land of Egypt was famished, the people cried to Pharaoh for bread: and Pharaoh said unto all the Egyptians, Go unto Joseph; what he saith to you, do. And the famine was over all the face of the earth: and Joseph opened all the storehouses, and sold unto the Egyptians; and the famine waxed sore in the land of Egypt. And all countries came into Egypt to Joseph for to buy corn; because that the famine was so sore in all lands.

And the sons of Israel came to buy corn among those that came: for the famine was in the land of Canaan.

For all this I considered in my heart even to declare all this, that the righteous, and the wise, and their works, are in the hand of God: no man knoweth either love or hatred by all that is before them.

Our skin was black like an oven because of the terrible famine.

Now there came a dearth over all the land of Egypt and Chanaan, and great affliction: and our fathers found no sustenance. But when Jacob heard that there was corn in Egypt, he sent out our fathers first. And at the second time Joseph was made known to his brethren; and Joseph's kindred was made known unto Pharaoh.
