Down from the Empyrean to forewarne
Us timely of what might else have bin our loss,
Unknown, which human knowledg could not reach:
For which to the infinitly Good we owe
Immortal thanks, and his admonishment
Receave with solemne purpose to observe
Immutably his sovran will, the end
Of what we are. But since thou hast voutsaf't
Gently for our instruction to impart
