OK. I've scrutinized the three passages in KJV. It appears to be no more or less "consistent" than any other translation.(My first choice was the New English Bible: Oxford Study Edition, because it has lots of footnotes.).

The only connection between the passages is that they predict a Messiah will be born. Nothing about frogprince's verse.

Still no bells. It's hopeless. I'm happy that you're happy, though.
