Here are the first two musical phrases:
In the second verse, the text here is "Thine over all shall be the praise / And thanks of ev'ry nation." "Nation" is sung with a melisma (E F G), giving a sense of amount (for "ev'ry"). The three syllables are also sung to all different pitches, and this adds to the effect, providing a sense of breadth.
In the third verse, the text is "O let the people praise Thy worth, / In all good works increasing." Here, "increasing" is sung with a melisma (F E F G), and since there's an extra syllable, there's a sense of the word's meaning.
