Then the lame will leap like a deer,
and the tongue of the mute will sing for joy,
for water will gush in the wilderness,
and streams in the desert;

Israel’s watchmen are blind, all of them,
they know nothing;
all of them are mute dogs,
they cannot bark;
they dream, lie down,
and love to sleep.

He was oppressed, yet when he was afflicted he did not open his mouth. As a lamb that is led to the slaughter, and as a sheep that before its shearers is mute, so he did not open his mouth.
