David is like a deaf mute (Ps 38:13-38:14)

“I am like the deaf ones.

I do not hear.

Like a mute

I cannot speak.

Truly,

I am like one

Who does not hear.

I am like one

In whose mouth are no rebukes.”

David has become like a deaf mute that can neither hear nor speak. Thus he does not hear anything and he cannot respond with rebukes.
