Juliet. Do not swear at all;

Or, if thou wilt, swear by thy gracious self,

Which is the god of my idolatry,

And I'll believe thee.

Romeo. If my heart's dear love—

Juliet. Well, [do not swear]. Although I joy in thee,

I have no joy of this [contract] to-night;

It is too rash, too unadvis'd, too sudden,

Too [like the lightning], which doth cease to be

Ere one can say it lightens. Sweet, good night!
