Kim Kardashian and Kris Humphries Get Biblical

Sources close to the couple tell TMZ they've been going over their favorite passages in hopes of picking a few to be engraved on their wedding bands. We're told Kim will pick a passage for Kris' ring, and Kris will pick one to be engraved on Kim's.

According to our sources ... they are each taking it very seriously and they both want to pick something "with meaning."

As we previously reported, Kim already has a bible verse engraved into her massive engagement ring.
