From TechCrunch:

eBible, a new Bible search engine, is currently in private beta

Search any of a number of versions of the Bible with eBible by keyword (and switch between Bible versions once you’ve selected text you are interested in). eBible pulls additional information relevant to your query from a library of Bible reference sites, such as dictionaries, topicals, encyclopedias, handbooks, etc. Expert commentary is also included in the margin of Biblical text.
