that is a free interlinear bible program. In my opinion it is the most useful software if you like looking at the original greek and hebrew for study. Way faster to use than blue letter bible’s website.
I would say the blue letter bible app for the phone is second best.
Adding a few more resources, my all time favorite as of late is Logos Bible Software. Highly recommend as it has thousands of hyperlinked resources to choose from. Countless translations, books, devotionals, commentaries, exgetical documents, cross referencing resources, greek and hebrew lexicons, etc. all in one application (Not everything is free though).
