The hosts of heaven give him glory;
before him tremble cherubim and seraphim;
let everything that has breath and all creation
praise him, bless him, and exalt him above all for ever.
You cover your high places with the waters,
you set the sand as a boundary to the sea and uphold all things:
the sun sings your praises,
the moon gives you glory,
all creatures offer a hymn to you,
their author and creator, forever.
Let all the trees of the forest dance and sing. . . .
Let the mountains and all the hills
break forth into great rejoicing at the mercy of God,
and let the trees of the forest clap their hands.
