Old Bible Handbook

Cleaning out my parents belongings I am finding things I have never seen in my life.  And some of it has been very interesting.

Take for instance this twenty-fourth edition, 1965, Halley's Bible Handbook complete with the Latest Archaeological Discoveries.  But the oddest note I found was this:

The Most Important Page in This Book is 814

And it's not the last page.  It is a suggestion as to what goes in a sermon or reading in the church.
