Upon every hill

This evening I stopped reading Words of Them Which Have Slumbered near the end of a section, having flipped forward a few pages to check. The next section, which I have yet to read, is called "Every Hill of Valinor."

Just now, on a random whim, I used a website to select a truly random verse from the King James Bible, something I haven't done in many months. I got this:

And there shall be upon every high mountain, and upon every high hill, rivers and streams of waters in the day of the great slaughter, when the towers fall (Isa. 30:25).
