Anyway

 Jacob's son's Joseph brothers get to Egypt but don't know Joseph is their brother 

Is a question

 I wasn't looking for the word 

Is the first time Isreal is

 Mentioned rather it be person or place 

And

 When God changed Jacob's name to Isreal 

 

They on their way to

 Egypt to buy food not knowing their brother Joseph is in charge 

There is famine in the land

 Jacob and his family know where to go and get everything ready for to buy food 

Pharaoh puts Joseph

 In charge of pretty much everything 

Joseph interprets

 A  dream for Pharoah gets out of prison 

Somebody finally remembered

 That Joseph could interpret dreams 

When they got out of prison

 They forgot about him
