It's quite an interesting name, I'm starting to like it more and more. And though it has a strong Biblical association, it's not like you're naming your child Delilah.
The more I look at this name, the more I like it. It sounds cool, has the very workable nickname "Bo," and the Boaz from the Bible was respectable and worth honoring. He was an ancestor of Christ, too. I'm definitely adding this to my list of boy names.
