King Henry VI, the third part

by William Shakespeare

RICHARD.
About that which concerns your Grace and us:
The crown of England, father, which is yours.

YORK.
Mine, boy? Not till King Henry be dead.

RICHARD.
Your right depends not on his life or death.

EDWARD.
Now you are heir, therefore enjoy it now.
By giving the house of Lancaster leave to breathe,
It will outrun you, father, in the end.

YORK.
I took an oath that he should quietly reign.

EDWARD.
But for a kingdom any oath may be broken.
I would break a thousand oaths to reign one year.

RICHARD.
No; God forbid your Grace should be forsworn.

YORK.
I shall be, if I claim by open war.

RICHARD.
I’ll prove the contrary if you’ll hear me speak.

YORK.
Thou canst not, son; it is impossible.
