This is the standard Greek lexicon for New Testament studies. I find that it takes longer to use than Louw and Nida, but gives a more mature understanding. It gives many more examples, and also points out grammatical features of the words, which can be extremely helpful. This lexicon does not attempt to give you a full dictionary definition; instead, it tries to give you the data to allow you to develop your own.
