'Deaf' in the Bible

To you I call, O Lord,My rock, do not be deaf to me,For if You are silent to me,I will become like those who go down to the pit (grave).

But I, like a deaf man, do not hear;I am like a mute man who does not open his mouth.

Their poison is like the venom of a serpent;They are like the deaf horned viper that stops up its ear,
