I smell active mold just looking at the pictures. Any book with active mold has about zero value to a collector. No one will risk such a book in their collection. Put your nose up against the Bible and take a big whiff.
Foxing, like you see on the example from eBay by History Teacher, is the residue from dry mold. Foxing can, for the most part, be neutralized and corrected. Foxing does reduce the value but it won't usually kill the salability of the book like live mold does.
If you believe your book is only smelly from being near other moldy books you can seal the book in a roasting bag with a healthy dose of baking soda. Pull the book out after 6 months, clean off the baking soda, and take another whiff. If it's odor free you are probably good to go but if you still smell mold you are probably better off to toss the book unless it's very valuable.
Generally old bibles don't carry much value. It's the most published book in the world so even older ones aren't usually rare. A known family connection with a written history included will usually double the value or more.
