"Thee Will I Love, My Strength, My Tower"

Earlier this month, I watched the Concordia University Wisconsin chapel service from the 5th.  The hymn was "Thee Will I Love, My Strength, My Tower," and I noticed a small feature in it.

The hymn is sung to the tune "Ich will dich lieben."  Here's the third musical phrase:

In the fourth verse, the text here is "Uphold me when my feet would stumble."  The phrase "Uphold me" is sung to an ascending group of notes (D F# A), giving something of a sense of its meaning.
