The first two lines of the hymn are "The Savior calls; let ev'ry ear / Attend the heav'nly sound," sung to this musical phrase:
The words "ev'ry ear" are sung to notes of all different pitches (B A G), and this provides a sense of the breadth of "ev'ry."
This feature is also in the third verse, which begins: "Here springs of sacred pleasures rise / To ease your ev'ry pain." At the end of the second phrase, "ev'ry pain" is sung to the pitches C B A.
I also noticed polysyndeton (the repeated "and") in the second verse: "Here streams of bounty flow / And life and health and bliss impart." This repetition gives a sense of that abundance.
