Genesis 47:18
When that year was ended, they came unto him the second year, and said unto him, We will not hide it from my lord, how that our money is spent; my lord also hath our herds of cattle; there is not ought left in the sight of my lord, but our bodies, and our lands:
This verse belongs to Joseph's dealings during the famine, when Egypt's abundant stored grain drew people from Canaan to buy food. It records the Egyptians' admission that their money was spent and their herds of cattle already belonged to Pharaoh, leaving nothing in his sight except their bodies and their lands. In exchange for food during the famine the Egyptians gave Pharaoh their lands and ultimately themselves. By contrast, Joseph's father and brothers did not make such a surrender but were granted land to live on because of Joseph's service to Egypt.
Joseph's father and brothers paid no tax and were supplied generously with food, in contrast to the Egyptians' hardship when their money had been spent and Joseph held their livestock and land. Egypt's abundance came through Joseph's wise management and was recognized as a blessing from Joseph's God.
