52:10

Rich Mullins names the song after its own source — "52:10" — then quotes Isaiah 52:10 almost without alteration: "the Lord has bared His holy arm in the sight of all the nations, and all the ends of the earth shall see the Lord's salvation." The prophecy's image of an exposed arm pictures strength no longer hidden, deployed openly rather than in reserve.

The song's extreme brevity — a handful of lines, repeated — matches its own content; a declaration about something made visible "in the sight of all the nations" doesn't need elaboration to make its point. Naming the song by its chapter and verse rather than a more evocative title keeps the focus on the text itself rather than on any original phrasing layered over it.
