The readings - days 83 and 84 - Judges 17-21
I had a professor once named Ephraim. He remains the only man I've ever met (or really even heard of) by that name.
Not that many of the names Jacob gave to his sons has really caught on through the centuries, other than Joshua, Benjamin (I'm pretty sure that most Dans are actual Daniels, so that doesn't count) and the occasional Levi. You don't meet a lot of Manessehs or Naphtalis these days, and as much as I'd love to, I'm pretty sure I'll never meet anyone named Zebulun.
