The Merchant of Venice
(Auto-generated)

Nerissa and the rest, stand all aloof; Let music sound while he doth make his choice; Then, if he lose, he makes a swan-like end, Fading in music: that the comparison May stand more proper, my eye shall be the stream And watery death-bed for him.†
Scene 3.2 *

aloof = socially distant or uninterested
Now he goes, With no less presence, but with much more love, Than young Alcides when he did redeem The virgin tribute paid by howling Troy To the sea-monster: I stand for sacrifice; The rest aloof are the Dardanian wives, With bleared visages come forth to view The issue of th' exploit.†
Scene 3.2
