In this week's Parasha Vayechi, there is a huge gap in the story. Ya'akov says he will tell his children what will happen to them at the end of days. Instead of revealing the plan of the final return to Israel, he blesses them. How can we explain this gap?
For genrations jewish parents have been blessing their children "May you be like Ephraim and Menashe".
Why were Yoseph's sons chosen over the three fathers to be the source for this blessing?
