The Tragedy of Julius Caesar by William Shakespeare (Act 3, Scene 1)

What does Mark Antony ask of the conspirators at the end of act 3, scene 1?

Post back with speed, and tell him what hath chanc'd: Here is a mourning Rome, a dangerous Rome, No Rome of safety for Octavius yet; Hie hence and tell him so. Yet, stay awhile; Thou shalt not back till I have borne this corse Into the market-place: there I shall try, In my oration, how the people take the cruel issue of these bloody men;

Antony asks that they allow him to take the body to the marketplace and, further, that he be allowed to orate at the funeral.

Here are the lines Antony delivers to the Servant (who is to take the news to the conspirators):

Ant.

Post back with speed, and tell him what hath chanc'd: Here is a mourning Rome, a dangerous Rome, No Rome of safety for Octavius yet; Hie hence and tell him so. Yet, stay awhile; Thou shalt not back till I have borne this corse Into the market-place: there I shall try, In my oration, how the people take the cruel issue of these bloody men; According to the which thou shalt discourse To young Octavius of the state of things. Lend me your hand.
