The Tempest -- IV. 1.

LOVE.

A murd'rous, guilt shows not itself more soon,

Than love that would seem bid: love's night is noon.

Twelfth Night -- III. 2.

Sweet love, changing his property,

Turns to the sourest and most deadly hate.

King Richard II. -- III. 2.

When love begins to sicken and decay,

It useth an enforced ceremony.
