The total number of Jacob’s direct descendants who went with him to Egypt, not counting his sons’ wives, was sixty-six. In addition, Joseph had two sons who were born in Egypt. So altogether, there were seventy members of Jacob’s family in the land of Egypt.

Genesis 46:26-27

Meanwhile, the people of Israel settled in the region of Goshen in Egypt. There they acquired property, and they were fruitful, and their population grew rapidly.
Genesis 47:27

• God is telling the story of redemption. 
• He built a family from one man. 
• He will build a nation from that family. 
• The Patriarchs are the ones which God tells us their stories: Abraham, Isaac, and Jacob. 
• Joseph is not in the direct line.
• The Messiah will come through the tribe of Judah. 
• The Joseph narrative explains how God’s people come to be in Egypt. 
• Joseph’s rise in power and the move of Jacob and his family meant that the people of God’s covenant promises were now living far from the Promised Land. 
• This DYSFUNCTIONAL family will now be away from home, where all that they have is each other. 
• God brought the nation Israel into existence for a purpose: to serve as His instrument of salvation for the world. 
• Genesis 12:2-3
• Genesis closes with the descendants of the Patriarchs living in exile in Egypt. 
• The ultimate fulfillment of the promises must await a later generation. 
• The promises of God are sure. 
• For as many as are the promises of God, in Christ they are [all answered] “Yes.” So through Him we say our “Amen” to the glory of God.
  2 Corinthians 1:20 (AMP)

Keep looking for the many ways that God, who is not bound by space or time, uses space, time, and His people to keep His promises. He never changes.
