This excerpt from Coriolanus contains every letter of the alphabet but Z:

O, a kiss
Long as my exile, sweet as my revenge!
Now, by the jealous queen of heaven, that kiss
I carried from thee, dear; and my true lip
Hath virgin’d it e’er since.

This one, from Milton’s Paradise Lost (from the Z in grazed to the b in Both), contains all of them:

Likening his Maker to the grazed ox,
Jehovah, who, in one night, when he passed
From Egypt marching, equalled with one stroke
Both her first-born and all her bleating gods.
