"Now Rest beneath Night's Shadow"

Last year, I noticed a couple small features in "Now Rest beneath Night's Shadow," sung to the tune "O Welt, ich muss dich lassen."  Here's the second musical phrase, which is also repeated as the fifth musical phrase:

In the fourth verse, the text sung to the second phrase is "Now spread Your wings above me," and the text sung to the fifth phrase is "Let angel guards sing o'er me."  In both of these, the musical pitches mirror the positions:  "wings" and "guards" (both sung to Gs) are above "me" (sung to an E both times).

"Arise and Shine in Splendor"

Last week, I transcribed the lyrics for "Arise and Shine in Splendor," and I noticed something about the first phrase.  In hindsight, it's obvious, but when sung to the melody "O Welt, ich muss dich lassen," the first part of the first line ("Arise and shine") ascends as if to musically represent the rising:

The same feature is present for the beginning of the fourth and fifth verses too:  "Lift up your eyes" and "Your heart will leap."

"O Welt, ich muss dich lassen"

This is the standard one-verse-of-one-arrangement-one-verse-of-an-other (LW 85 and LSB 396).  I'm pretty sure I read and played the notation correctly; it's just that both have some weird harmonies.
