"Spread the Reign of God the Lord"

Recently, I happened to see the title "Spread the Reign of God the Lord" and realized a way in which it connects to the melody to which it's sung, the first phrase of the tune "Gott sei Dank":

The phrase spans an octave, musically reflecting this idea of "spread[ing]."

"Spread the Reign of God the Lord"

Last year, I noticed a detail in "Spread the Reign of God the Lord," sung to the tune "Gott sei Dank."  Here's the third phrase:

In the first verse, the text here, describing where the reign of God is to be spread, is "Ev'rywhere His creatures call."  "Ev'rywhere" is sung with a melisma (G C B A), and each syllable is sung to a different pitch.  Both of these features provide a sense of breadth.
