I figured it was the quintessential version of the Bible ¯\_(ツ)_/¯. I'm not religious so cut me some slack haha. Looking back, I should've used a version using modern English.
KJV is still wildly popular and some sects even regard it as an inspired translation. Never heard that about anything else.
NKJV is more readable for people who grew up reading blog posts instead of old books and generally retains the poetry of the KJV, but it's under copyright. I think it would be allowed for a use like this though, because they explicitly allow (as do most translations) quoting up to a certain number of verses.
My understanding of the Eastern Orthodox Church is that they see the Septuagint as an inspired translation of the Old Testament (from Hebrew to Koine Greek).

Seems like you'd fall afoul for the % of total text requirement.
