How does rhyme reinforce the stanza pattern in George Herbert’s “Vertue”?

In George Herbert’s poem "Vertue," rhyme serves as a structural device that "clinches" the stanzaic form, reinforcing the poem's recurring set of lines.1

The poem is composed of stanzas consisting of three lines of iambic tetrameter followed by one line of iambic dimeter. Within this structure, the rhyme scheme binds the lines together by ensuring that the first and third lines, as well as the second and fourth lines, end with matching sequences of vowels and consonants (such as bright/night and skie/pie). By echoing the final sounds of these lines, the rhyme provides a sense of closure and unity to each stanza, effectively anchoring the rhythmic pattern established by the metre.12
