Near the end of the first verse, there's the line "The gifts He gives to ev'ryone," sung to this phrase from the tune "Nun freut euch":
The three syllables of "ev'ryone" are each sung to a different pitch (A G F), and this gives a sense of that breadth.
There's a similar feature in the third verse. In the middle, there are the lines "The water of your Baptism day / Restored again whatever / Old Adam and his sin destroyed." The line "Restored again whatever" is sung to this phrase:
"Whatever" is sung with a melisma, and each syllable is sung to a different pitch (G D E F). This too gives a sense of breadth.
