Read the full text of Henry VI Part 2 Act 3 Scene 3 with a side-by-side translation HERE.
Henry, Warwick, and Salisbury visit Cardinal Beaufort on his deathbed.
Cardinal Beaufort thinks Henry is Death itself and asks if he will leave. No can do: Henry is not Death, and he's going to stick around.
Then Beaufort mentions Gloucester and says he will confess. Just bring him some food, drink, and medicine to help him.
Henry notices that Beaufort is in a lot of pain: that means he has done wrong and is guilty.
The other men notice it, too—Beaufort is not dying peacefully. Then Henry tells him to give a signal of hope, but Beaufort dies without making the sign. Henry figures that means Beaufort needs to be forgiven.
While Warwick judges Beaufort for the horrible life he lived, Henry chides him. We're all sinners, Henry says. Let's go meditate.
