In Julius Caesar, what are the line numbers and scene where Brutus is torn between his friendship with Caesar?

Julius Caesar, 2.1.10-34

It must be by his [Julius Caesar's] death; and, for my part,
I know no personal cause to spurn at him,
But for the general...
The abuse of greatness is when it disjoins
Remorse from power, and — to speak truth of Caesar —
I have not known when his affections swayed
More than his reason...
that what he is, augmented,
Would run to these and these extremities;
And therefore think him as a serpent's egg —
Which, hatched, would, as his kind, grow mischievous —
And kill him in the shell.
