A couple months ago, one of the hymns in church was "I Come, O Savior, to Thy Table." I realized something about the beginning of the fourth verse. The first line is "Weary am I and heavy laden," and the melody there (in the tune "Ich sterbe täglich") descends, portraying both weariness and being heavy laden:
"Laden" is even sung with a melisma, which emphasizes the effect.
Additionally, while it doesn't seem to have any connection to the hymn text, there's a cross inscription in the second measure.
