Day 19 - A song from your favorite album

I don't know/i'm not sure what my fave album ever is...but for a while i have considered my fave U2 album to be War.
A lot of good songs on that, but one of the lesser-known good ones from that album is "Drowning Man."

Rise up, rise up
With wings like eagles
You'll run
You'll run
You'll run and not grow weary.

Kudos to whoever can tell me what literary work those lines were alluding to.
