I watched it twice last night or most of it twice. In the Sodom scene they did seem to show all behaviors but it was taking place in the background. The two hooded guys going into Sodom were angels of course. BTW Isaac and Ishmael were separated. However not for good. They were united again for Abraham's burial. People also forget to factor in Abraham's other sons form a marriage after Sarah's death. They too were separated from Isaac.
The third person who visited Abraham was The Lord appearing to Abraham as stated in Genesis 18.
They also did mention that Jacob's name would be changed to Israel.
I must rewatch it because I definitely did NOT hear anything about Jacob's name change, but things were flying by sort of out of context that if one didn't understand the whole story, one would certainly wouldn't know it after watching the program.
Especially, most non-bible readers or students of the bible wouldn't bother to watch this moe than once.
