And God forgive them that so much have swayed

Prince Hal
And God forgive them that so much have swayed
Your Majesty’s good thoughts away from me.

And I will call him to so strict account
That he shall render every glory up,
Yea, even the slightest worship of his time,
Or I will tear the reckoning from his heart.

I will redeem all this on Percy’s head,
And, in the closing of some glorious day,
Be bold to tell you that I am your son,
When I will wear a garment all of blood
And stain my favors in a bloody mask,
Which, washed away, shall scour my shame with it.
And that shall be the day, whene’er it lights,
That this same child of honor and renown,
This gallant Hotspur, this all-praisèd knight,
And your unthought-of Harry chance to meet.
For every honor sitting on his helm,
Would they were multitudes, and on my head
My shames redoubled! For the time will come
That I shall make this northern youth exchange
His glorious deeds for my indignities.
Percy is but my factor, good my lord,
To engross up glorious deeds on my behalf.
And I will call him to so strict account
That he shall render every glory up,
Yea, even the slightest worship of his time,
Or I will tear the reckoning from his heart.
This in the name of God I promise here,
The which if He be pleased I shall perform,
I do beseech your Majesty may salve
The long-grown wounds of my intemperance.
If not, the end of life cancels all bands,
And I will die a hundred thousand deaths
Ere break the smallest parcel of this vow.
King 
A hundred thousand rebels die in this.
Thou shalt have charge and sovereign trust herein.
