The first line of the second verse is "What the fathers most desired," and the first line of the third verse is "Abram's promised great reward." "Most" and "great" are both sung with a melisma (A G), musically giving something of a sense of degree.
This same musical phrase is repeated at the end of the hymn, and there are some significant melismas in the text there too. The last line of the third verse is "Truly came, as long foretold," and the last line of the fourth verse is "Which is Your eternally." "Long" (A G) and "eternally" (Bb A G A G) are both sung with melismas for a sense of duration.
