'Dumb' in the Bible

Then the lame will leap like a deer,And the tongue of the mute will shout for joy.For waters will break forth in the wildernessAnd streams in the desert.

Who [among the idols] has declared this from the beginning, so that we could know?Or from earlier times, so that we could say, “He is [unquestionably] right!”?In fact, there was no one who declared it,Indeed, there was no one who proclaimed it;There was no one at all who heard you speak [for you pagan gods are speechless].

He was oppressed and He was afflicted,Yet He did not open His mouth [to complain or defend Himself];Like a lamb that is led to the slaughter,And like a sheep that is silent before her shearers,So He did not open His mouth.

Israel’s watchmen are blind,They are all without knowledge.They are all mute dogs, they cannot bark;Panting, lying down, they love to slumber.
