WP-Bible searches your posts and pages for any reference to a Bible passage and converts the reference to an actual biblical text – which can be any of the 38 translations (in 14 different languages) that you can see at BIBLIJA.net. Or, you can select that plugin only makes links to the biblical text.
No special tagging of biblical references is needed, the plugin recognizes different (up to 12) names for the same book in the Bible (for example: you can type Matthew 5:1-11 or Mat 5:1-11 or Mt 5:1-11 or you can even use other standards for marking biblical references like Mat 5,1-11.15-17;6,1-3. All this will do. Plugin then changes the reference for a link and when you click the link a small layer is shown above containing the biblical text. No opening other windows, no popups.
