Lestat quoting Othello (Act 5, scene 2), in Interview with the Vampire (strike-throughs are words cut out, and the last line is different, too):

“Yet she must die, else she’ll betray more men.

Put out the light, and then put out the light.

If I quench thee, thou flaming minister,

I can again thy former light restore

Should I repent me. But once put out thy light,

Thou cunning’st pattern of excelling nature,

I know not where is that Promethean heat

That can thy light relume. When I have plucked thy rose

I cannot give it vital growth again,

Its needs must wither.”
