Robert Herrick - The Bellman

From noise of scare-fires rest ye free,
From murders Benedicite.
From all mischances that may fright
Your pleasing slumbers in the night :
Mercy secure ye all, and keep
The goblin from ye while ye sleep.
Past one o'clock, and almost two,
My masters all, good-day to you.

Robert Herrick
