"Rejoice, My Heart, Be Glad and Sing"

Last year, I transcribed the text of "Rejoice, My Heart, Be Glad and Sing" (sung to the tune "Ich singe dir") and noticed a small feature.  Here's the third musical phrase:

In the first verse, the text here is "For God, the source of ev'rything" (the next line is "Your portion shall remain").  Each syllable of "ev'rything" is sung to a different pitch (Eb D C), and this gives something of a sense of breadth and entirety.
