Type in the word you want to search for, select the Bible version you want to use (if it is not the one already selected) and click on 'search'.

Below the entry form a list of results will appear (you can set the length of this list in preferences).  If the list of references found is to long, then multiple pages will be created.  Use the 'previous' and 'next' buttons to navigate through these pages.  Click on the 'clear' button to clear the search.  To view one of the references returned by the search just click on the reference in the search list.

The word that you have searched for will be highlighted in the text - if the case matches.  However, the search itself is not case sensitive

Tip: Pick a version with Strongs numbers (eg KJV), toggle Strongs on and then you can enter a number to search the Bible on Strongs numbers!  Don't forget that Strongs greek and hebrew numbers will have different meanings.
