"Word of God, Come Down on Earth"

Years ago, I wrote about some small features in "Word of God, Come Down on Earth," but when it was in a Concordia University Wisconsin chapel service recently (on the 4th), I noticed an-other small point.

The hymn is sung to the tune "Liebster Jesu, wir sind hier."  Here's the second-to-last phrase:

In the fourth verse, the text here is "Word of truth, to all truth lead us."  The second "truth" is sung with a melisma (A G), giving a sense of the entirety of that modifying "all."
