"Sing to the Lord of Harvest"

Last year, I noticed a small feature in "Sing to the Lord of Harvest," sung to the tune "Wie lieblich ist der Maien."  Near the end of the second verse, there are the lines "God fills them [hills and valleys] with His fullness, / All things with large increase."  That second line is sung to this phrase:

The phrase "large increase" is sung with melismas (C B | A G A), and this articulation provides a sense of that abundance.
