No More Learning

And forasmuch as we learn in our books that
thou never workest miracles, but to divine and           end, (for the
laws of nature are thine own laws, and thou exceedest them not but upon
great cause,) we most humbly beseech thee to prosper this great sign,
and to give us the interpretation and use of it in mercy; which thou
dost in some part secretly promise by sending it unto us.
