I've written about small features in "Come, Ye Thankful People, Come"
twice before, but I found an-other one when I was looking at the hymn a couple months ago. The third verse begins with the lines "For the Lord, our God, shall come / And shall take His harvest home, / From His field shall in that day / All offenses purge away." The third and fourth lines are sung to these musical phrases from the tune "St. George's, Windsor":
The phrase "all offenses" is sung to notes of all different pitches (spanning a fifth: A B C F), providing a sense of this entirety. Since one of these notes is an accidental (a B natural in F major), there's an even greater sense of totality or, alternatively, a sense of the meaning of "offenses."
