In doing word counts in 1 Peter, using the KJV, I have found a couple of discrepancies—there may be more. In 1:18, the word πατροπαραδοτος (which only occurs here) is listed as occurring 6 times! Similarly, the word ευαγγλιζο is listed as occurring 6 times, while in reality it only occurs twice.
I'm using L6. I'd be grateful if someone can shed light on this. I have checked with the ESV and everything is fine with the word list.
