Thomas Aquinas, on Ps 8:9

“The birds of the air, and the fishes of the sea, that pass through the paths of the sea.”

“Just as God is admirable for the eminence of his majesty, so he is shown to be admirable from his clemency; and therefore he concludes with wonder: "Lord, our Lord," etc. Yet it should be known that this Psalm is circular, because it has the same verse at the beginning and at the end. Some are semicircular, because they do not repeat the whole verse, but a part; such as "Bless the Lord, O my soul," whose end is "in every place of his dominion."”
