"I Know My Faith Is Founded"

I wrote about a small feature in "I Know My Faith Is Founded" about a year ago, but when it was one of the hymns on Worship Anew last month (5 October, Seventeenth Sunday after Pentecost), I noticed something else.

The fourth line of the first verse is "Unmoved I stand on His sure Word," sung to this musical phrase from the tune "Nun lob, mein' Seel'":

The words "Unmoved I stand" are all sung to the same pitch, and this musical constancy matches the meaning.
