“Sweet are the uses of adversity”- from which Shakespeare's play, the quotation is taken from?

“Sweet are the uses of adversity,
Which, like the toad, ugly and venomous,
Wears yet a precious jewel in his head;
And this our life, exempt from public haunt,
Finds tongues in trees, books in the running brooks,
Sermons in stones, and good in every thing.”

― William Shakespeare, As You Like It
