"My Faith Looks Up to Thee"

Back in August last year, I noticed a small feature at the end of the first verse of "My Faith Looks Up to Thee."  The last two lines are:  "O let me from this day / Be wholly Thine!"  They're sung to these phrases from the tune "Olivet":

"Wholly" is sung with a fairly large interval (a fourth:  E A), which helps give a sense of entirety.

Last week, I was looking at the hymn again, and I thought that I'd markt "wholly" for a different reason:  it's sung to two half notes, so in terms of note values, it takes up the whole of that measure.
