Tapping into the amazing minds of my Logos family both in knowledge of history and knowledge of Logos...
Years ago I heard about a custom that some Jewish families practiced. It involved the sacrificial lamb for Passover, and that families would keep the lamb around the house for a time - I can't remember how long - to the point where the family would form a bond, like a pet. Then when it came to sacrifice the lamb, the gravity of the sacrifice became more clear.
I refuse to tell "preacher stories." I must know if this (or anything close to it) is true in Jewish custom either past or present. I can't seem to find it anywhere and can't remember where I first heard it. For all I know, it was a "preacher story" that got stuck in my head.
So:
First, have any of you heard of this?
Secondly, if you have, could you point me toward a reliable source, preferably in Logos?
I really appreciate this. If it has a basis in truth, it is going to make an awesome sermon illustration (with a real lamb), but I won't sacrifice the poor thing! 
You might even be able to guess where I might go with it.
Help? Thanks!
