Attempting to solve Luskin's "High-Speed Telescopic Evidence"

I figure "If red ran thy troubled waters?" is a cryptic clue of sorts and whatever it was would end up being a book of the Bible and would work in conjunction with "5:10" to give a chapter and verse.

But I'm horrible at cryptics. "If red ran" = pink? Troubled "waters" = rawest? Although raw meat is kind of pink, probably not. Maybe "If red ran thy" troubled = fire hydrant? A fire hyrant uses a hose to "water" fires... "a hose" = Hosea? Hosea 5:10 (RS) reads:

The princes of Judah have become
like those who remove the landmark;
upon them I will pour out
my wrath like water.

Interesting, since I'm probably looking for a landmark and it does have the water connection. But then what? Is there a landmark at the corner of Prince and Judah? A fountain, maybe?
