“In this close hand of Love, now soft and warm” (alliteration) The repetition of the “s” sound in “close” and “soft” creates a soothing effect, just as the speaker banishes pain with the gentleness of her love.
“And let us hear no sound of human strife” (alliteration) The repetition of the “s” sound in “us,” “sound,” and “strife” once again creates a soothing effect. The speaker is proposing a loving solution to the hate of the world.
“Life to life” (alliteration and assonance) The repetition of the word “life” flows off the tongue and stresses the importance of the speaker and her husband to each other’s lives. Both the “l” and the long “i” sound contribute to this effect.
“The lilies of our lives” (alliteration) The “l” repetition has a calming effect and once again conveys the speaker’s gentle tone.
“Alone to heavenly dews that drop not fewer” (alliteration) The repetition of the “d” sound resembles the dropping sound of water, like the dew mentioned in the line.
“I lean upon thee” (assonance) The long “e” sound in “lean” and “thee” has a harmonious effect, depicting the speaker’s joy in being able to trust her husband.
“That drop not fewer” (assonance) The back-to-back “o” sound in “drop” and “not” gives the line a heavy sound, like the sound of a drop.
