I know that years ago this resource was available for e-sword in both a free and limited version and also as a premium module. Or, that is what I recall. Having searched the internet for one for e-sword today, I find nothing. Can anyone please comment?
The good news is that it has its own iPad app and it is free.
The premium used to be available at www.bible.org - I snooped for a link but found none, you might email them. The free one should be around, maybe someone knows a source for it. Hopefully someone will post it for you.
