Reply To: The last thing I would think of is Mayim Acharonim

Haleivi: First, what source do you have for that?

Secondly, my question is still standing:

Well, in the Netilas Yadaim story, it makes sense. There’s a direct connection between washing Netilas Yadaim and being identifiable as a Jew.

There is not such a direct connection between washing Mayim Acharonim and killing one’s wife.
