"Light of the World"

I recently ran across a reference to "You are the light of the world" from Matthew 5:14.  Later, it occurred to me that the phrase "light of the world" is also in an Alan Parsons Project song (the title phrase, even).

When I lookt at the lyrics, I noticed the line "I am just a stranger in a promised land," and I realized that this bears some resemblance to part of Exodus 2:22:  "I have been a stranger in a strange land."  "Strange land" from Exodus has just been replaced with "promised land," which also has Biblical connotations.
