Upon my sword.
MARCELLUS
We have sworn, my lord, already.
HAMLET
Indeed, upon my sword, indeed.
Ghost
[Beneath] Swear.
HAMLET
Ah, ha, boy! say'st thou so? art thou there,
truepenny?
Come on--you hear this fellow in the cellarage--
Consent to swear.
HORATIO
Propose the oath, my lord.
HAMLET
Never to speak of this that you have seen,
Swear by my sword.
Ghost
[Beneath] Swear.
HAMLET
Hic et ubique? then we'll shift our ground.
Come hither, gentlemen,
And lay your hands again upon my sword:
Never to speak of this that you have heard,
Swear by my sword.
Ghost
[Beneath] Swear.
HAMLET
Well said, old mole! canst work i' the earth so fast?
A worthy pioner! Once more remove, good friends.
