Many other resources also make use the Strong's numbers. Some of the other translations also have concordances compiled for them.

One can find a commentary on a particular book of the bible or a series of commentaries that cover several books or even the entire bible. One problem with a commentary is that the writer often has a particular perspective that dominates his exploration of a passage such that other views are not considered. A more helpful type of commentary is one where the author gives several views for a particular verse.
