The sun descending in the west.

The evening star does shine,

The birds are silent in their nest.

And I must seek for mine.

The moon, like a flower

In heaven's high bower,

With silent delight

Sits and smiles on the night.

Farewell, green fields and happy grove,

where flocks have taken delight

Where lambs have nibbled, silent move

The feet of  angels are bright,

 Unseen they pour blessing

and joy without ceasing

on each bud and blossom, 

and each sleeping bosom.

They look in every thoughtless nest

where birds are covered warmly,

they visit the caves of every beast,

to keep them all from harm.

if they see any weeping 

that should have been sleeping,

they put to sleep on their head,

and sit down by their bed.
