'Deaf' in the Bible

A Psalm of David.To You, O Lord, I call;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.

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

They have venom like the venom of a serpent;Like a deaf cobra that stops up its ear,
