In the second verse, the text is "Take away the love of sinning." Here, "away" is sung with a melisma (C C Bb), giving a sense of (metaphorical) movement.

The sixth musical phrase:
In the first verse, the text here is "Pure, unbounded love Thou art." The words "unbounded love" are sung with melismas (A A Bb C | C Bb), and since the words aren't limited to their usual amount of syllables, there's a sense of the meaning of "unbounded."
