Scattered throughout Knuth's programs are a number of great comments. I really enjoy encountering these and I thought I'd share them. (As I wrote in my first post, this blog is mostly a way for me to collect pieces of information. As such, I'm mostly collecting these quotes for me.)

In tex.web, line 950 is

last:=first; {cf.\ Matthew 19\thinspace:\thinspace30}

This line of code is assigning first to the variable last. You can find many versions of that verse here. The King James version is

But many [that are] first shall be last; and the last [shall be] first.
