All things that you should use to do me wrong Deny their office; only you do lack That mercy which fierce fire and iron extends, Creatures of note for mercy-lacking uses. HUBERT.

“An if you do, you will but make it blush And glow with shame of your proceedings, Hubert. Nay, it perchance will sparkle in your eyes, And, like a dog that is compell'd to fight, Snatch at his master that doth tarre him on. All things that you should use to do me wrong Deny their office; only you do lack That mercy which fierce fire and iron extends, Creatures of note for mercy-lacking uses. HUBERT. Well, see to live; I will not touch thine eye For all the treasure that thine uncle owes. Yet I am sworn, and I did purpose, boy, With this same very iron to burn them out. ARTHUR. O, now you look like Hubert!” source
