2) From the More dropdown, choose Indexes.
3) Choose Bible Citation from the Browse an Index dropdown, then type in the scripture passage you would like to search.
4) Click on Search and you will get relevant choices. Check the boxes you would like to search.
5) Click Search again to get the results.
