"O Jesus Christ, Thy Manger Is"

When I recorded "O Jesu Christ, dein Kripplein" back in September, I noticed a small connection between it and the text "O Jesus Christ, Thy Manger Is" (TLH #81).  (In The Lutheran Service Book, "O Jesus Christ, Thy Manger Is" [#372] is sung to the tune "In paradisum.")

Here's the second musical phrase:

In the first verse, the text here (describing the manger) is "My paradise at which my soul reclineth."  The phrase "my soul reclineth" is sung to a descending group of notes (Bb Ab G F Eb), musically giving a sense of this "reclin[ing]."
