Crosswalk.com: Greek & Hebrew Interlinear BibleLook up English words to find Greek and Hebrew passages. In any verse displayed you can click on the Greek or Hebrew word to see its entry in a lexicon (Brown, Driver, and Briggs' Gesenius Lexicon and the New Testament Greek Lexicon based on Thayer's and Smith's Bible Dictionary). Greek entries are keyed to the Theological Dictionary of the New Testament, and Hebrew entries are keyed to the Theological Word Book of the Old Testament.
In order to view the Greek or Hebrew text you must install BST Fonts on your system (free copies available on this website).
