by the Priestess's palace
of the mighty gods:
together with the pines, its
reflections shall stay clear
Meaning
The Arisu River that flows by the palace of the Kamo Priestess will surely keep its reflections clear forever, together with the pines, just as the Priestess will long dwell there.
Commentary
Book Ten Poems of Celebration 616

Headnote: "Composed on the topic 'Pine Boughs Reflected in the Water' at the main palace, when the Nijō Grand Empress Dowager was still the Kamo Priestess"
Composed on the topic "Pine boughs reflected in the water" at the main palace of the Kamo Priestess in Murasakino, when the Nijō Grand Empress Dowager, Princess Reishi, was still the Priestess. The Arisu River at the Priestess's palace, he says, will keep its reflections clear together with the pines. In the clear reflection of the pine boughs on the water he sees the Priestess dwelling there for long ages, and so celebrates her. Princess Reishi was a daughter of Emperor Shirakawa and later became Grand Empress Dowager.
The author, "the Kyōgoku Former Chancellor," is Fujiwara no Morozane. The son of Regent Fujiwara no Yorimichi, he served in turn as Regent, Chancellor and Grand Minister, and was called the Kyōgoku Lord.
The preceding poem, 615, was composed at a poetry contest at Morozane's residence and counted a thousand ages in the waves of the Uji River. This poem sees permanence in the pines reflected in the Arisu River, so that poems of celebration through rivers follow one another.

First line, "chihayaburu": a pillow word attached to "god" and things related to the gods, here to "itsuki no miya." Poems 621 and 635 of this book open with the same pillow word.
Second line, "itsuki no miya no": "itsuki no miya" is the palace of the Priestess who served the Kamo deities.
Third line, "Arisugawa": the Arisu River flowed near the main palace of the Priestess in Murasakino.
Fourth line, "matsu to tomo ni zo": "together with the evergreen pines," taking up "pine boughs" in the topic. The emphatic "zo" closes with the attributive "beki" in the last line.
Fifth line, "kage wa sumu beki": "sumu" combines "to be clear," said of the reflection in the water, and "to dwell," said of the Priestess. "Beki," the attributive of the conjectural "beshi," closes the "zo" of the fourth line.
