Rob,
I simply cannot understand you. You show you do not know the story of Joseph:
"Over four hundred years and through thousands(or even millions) free will choices..."
Joseph was Jacob's son. Jacob was Isaac' son. Isaac was 66 when Jacob was born. Isaac was Abraham's son. This is not a 400 year prophecy. They were enslaved relatively soon after God told Abraham about it.
They lived in Egypt 430ish years from Joseph to Moses.
Exodus 12:41
And it came to pass at the end of the four hundred and thirty years—on that very same day—it came to pass that all the armies of the LORD went out from the land of Egypt.
Joseph and the entire group that lived in Egypt died before they were enslaved:
Exodus 1
1 Now these are the names of the children of Israel who came to Egypt; each man and his household came with Jacob: 2 Reuben, Simemon, Levi, and Judah; 3 Issachar, Zebulun, and Benjamin; 4 Dan, Naphtali, Gad, and Asher. 5 All those who were descendants[a] of Jacob were seventy persons (for Joseph was in Egypt already). 6 And Joseph died, all his brothers, and all that generation. 7 But the children of Israel were fruitful and increased abundantly, multiplied and grew exceedingly mighty; and the land was filled with them.
8 Now there arose a new king over Egypt, who did not know Joseph. 9 And he said to his people, “Look, the people of the children of Israel are more and mightier than we; 10 come, let us deal shrewdly with them, lest they multiply, and it happen, in the event of war, that they also join our enemies and fight against us, and so go up out of the land.”
We are talking 3 or four generations later. Jacob, Joseph, and his sons all had to die before you can even star to count the years of their enslavement. What's a fair number, Rob? 3 Generations, pushing it, making it as short as possible... 100 years?
430-100 = 330 years of actual enslavement?
And what was the prophecy again?
Genesis 15
Then He said to Abram: “Know certainly that your descendants will be strangers in a land that is not theirs, and will serve them, and they will afflict them four hundred years..."
Clearly... Rob. The Jews were not slaves a total of 400 years. Yeah, they were THERE 430.. However, "they will afflict them four hundred years," was not accurate.
Didn't God know the years? Didn't he foresee it exactly? No. He took a stab at it. As time went on, 400 years was feeling like too much, God heard their cries and jumped ahead to free them before the appointed time:
Exodus 3:9 Now therefore, behold, the cry of the children of Israel has come to Me, and I have also seen the oppression with which the Egyptians oppress them.
Slaves only 300 years.. maybe less?
Why doesn't this compel you to reevaluate the S.V.?
