"Rejoice, O Pilgrim Throng"

A couple years ago, I noticed two small features in "Rejoice, O Pilgrim Throng."  Both are in the third musical phrase of the tune "Marion":

In the first verse, the text here is "Your festal banner wave on high."  "Wave" is sung with a melisma (A G), musically giving a sense of that movement.

In the third verse, the text is "Pour out the strains of joy and bliss."  Here, "joy" is sung with the same melisma, giving a sense of that ebullience.
