To scriptor-ga, 

I would say "the most commun one in english language".

Here it is:

E-SWORD
http://www.e-sword.net/

It has dozens of languages, dozens of commentaries, multiple of
versions, maps, dictionaries, you name it this one has it ~AND~ It's
updated often. See for yourself:

It's free to those who cannot pay. I use it regularly in my own
studies and I am tremendously grateful for it and for the program's
creator, Rick Meyers, who says:

"Without payment you have received; without payment you are to give."
(Mat 10:8 ISV)

So, there. Now you have it. Enjoy.

Thanks but I actually plan to use it for business. 

Should I start to consider paying some copyright fee ..?

Don't know. You might contact Rick Meyers and see if he minds you
using his software in your business. If it's for a good cause he may
give you permission, who knows. Can't hurt to ask.
