どこかでみた

お日様に誓って言うが、そのつもりだった、
お前と一緒に寝るまでは。

Hamlet でした。Act 4, Scene 5。

By Gis and by Saint Charity,
Alack, and fie for shame!
Young men will do't, if they come to't;
By cock, they are to blame.
Quoth she, before you tumbled me,
You promised me to wed.
So would I ha' done, by yonder sun,
An thou hadst not come to my bed.
