Chigiriokishi hito mo kozue no ko no ma yori tanomenu tsuki no kage zo morikuru - Kinyo Wakashu(English Translation & Meaning)

契りおきし人もこずゑの木の間より
頼めぬ月の影ぞ漏り来る

Roma-ji: Chigiriokishi hito mo kozue no ko no ma yori tanomenu tsuki no kage zo morikuru
English Translation: The one who promised
has not come, yet through the trees,
between treetop boughs,
the moon that made no promise
lets its light come stealing in
Meaning: The one who made a promise does not come; instead, through the treetops, the light of the moon that promised nothing comes stealing in.
Commentary: Book Eight Love Poems II 470

The one who promised to come does not come, the poet says, yet through the treetops only the light of the moon, which promised nothing, comes stealing in. Punning on kozu, does not come, and kozue, treetop, the poem conveys the loneliness of a night of waiting through the moonlight that visits in place of the one awaited.
Poem 424 in this book sings that no promise to look at the moon was made, and this poem too sings of a moon that promised nothing, the two sharing a link between promises and the moon.

First line, 'chigiriokishi', means who had promised, using shi, the attributive of the past ki, in a line with an extra syllable.
Second line, 'hito mo kozue no', is a pivot word in which kozue means both the person not coming and the treetops, left in kana.
Third line, 'ko no ma yori', means from between the trees.
Fourth line, 'tanomenu tsuki no', means of the moon that gave no promise, set against the person who did.
Final line, 'kage zo morikuru', means its light comes stealing in, the particle zo answered by the attributive kuru.
