What is the famous quote that ends with "...and the rest is silence." Where is this from and how does it begin?

O, I die, Horatio;
The potent poison quite o'er-crows my spirit:
I cannot live to hear the news from England;
But I do prophesy the election lights
On Fortinbras: he has my dying voice;
So tell him, with the occurrents, more and less,
Which have solicited. The rest is silence.

This is a Shakespeare quotation.These are Hamlets last words.
O, I die, Horatio;
The potent poison quite o'er-crows my spirit:
I cannot live to hear the news from England;
But I do prophesy the election lights
On Fortinbras: he has my dying voice;
So tell him, with the occurrents, more and less,
Which have solicited.--the rest is silence.
Act 5, scene 2,l.
