The second line of the second verse is "All generations laud and honor thee," sung to this musical phrase from the tune "Gabriel's Message":
The phrase "All generations" is sung to the notes D G Bb A C. That these pitches span nearly an octave also lends a sense of this breadth.
The third line of the fourth verse is "And Christian folk throughout the world will ever say," sung to this musical phrase:
"Throughout the world" is sung to the notes A Bb C D. Additionally, the note values lengthen at the end of the phrase (with "say" sung to the longest, five beats), illustrating the duration of "ever."
