"Now That the Daylight Fills the Sky"

"Now That the Daylight Fills the Sky" was one of the hymns in an online church service I watched about a month ago.  I don't think I've ever sung (or even heard) this hymn before, but I found a few interesting features in it.  It's sung to the tune "Laurel."  Here's the first phrase:

The first line is, of course, "Now that the daylight fills the sky."  "Daylight" is sung with a melisma (D F# G), musically giving something of a sense of abundance (for "fill[ing] the sky").  The fourth verse is a doxology, which begins, "All praise to You, creator Lord!"  That "All" is also sung with a melisma (D E), for a sense of entirety.

There's a similar feature in the second line of the fourth verse:  "All praise to You, eternal Word!"  Here's the notation:

The specific melisma for this "All" is different (A B), but the idea is the same.  Additionally, "eternal" is sung with a melisma (G# A F# F#), giving a sense of duration.
