If I may have it when it's dead

If I may have it when it's dead
I will contented be;
If just as soon as breath is out
It shall belong to me,

Until they lock it in the grave,
'T is bliss I cannot weigh,
For though they lock thee in the grave,
Myself can hold the key.

Think of it, lover! I and thee
Permitted face to face to be;
After a life, a death we'll say, --
For death was that, and this is thee.
