"Come, Thou Almighty King"

I've written about small features in "Come, Thou Almighty King" twice before, but I found an-other one a couple months ago.  Near the end of the third verse, there are the lines "Thou, who almighty art, / Now rule in ev'ry heart," sung to these musical phrases from the tune "Italian Hymn":

The phrase "ev'ry heart" is sung to notes of all different pitches (A G F), giving a sense of number.
