"Do not go for advice to people who consult the dead..." Lev 19:31
I'm curious as to what prompted this highlight in George's Bible. Perhaps he was speaking to someone who asked about this, or had done it. It does raise an interesting question though - when you need advice or inspiration, where or who do you go to for it?
The end of this verse (unhighlighted in George's Bible) says:
"I am the Lord your God."
I'm almost certain it's there to answer exactly that question.
