"Chief of Sinners Though I Be"

I didn't make a note of the circumstances, but last year, I noticed a small feature in "Chief of Sinners Though I Be," sung to the tune "Gethsemane."

The last two phrases of the hymn are sung to conjunct melodies:

There is a break in between the two phrases, but otherwise, there aren't any leaps in the tune.  In a word, it's step-wise, and this has a musical connection with the lines about walking at the end of the third verse: "Faith and hope to walk with God / In the way that Enoch trod."
