"Good Christian Friends, Rejoice and Sing"

A couple months ago, I was flipping through the hymnal, and I happened to notice a small feature in "Good Christian Friends, Rejoice and Sing."  It's sung to the tune "Gelobt sei Gott."  Here's the third musical phrase:

In the first verse, the text here is "To all the world glad news we bring," and in the second verse, the text is "Let all the world rejoice and say."  In both, the words "all the world" are all sung to different pitches (E A G), providing a sense of the breadth or entirety of that "all."
