Psalms 38:13 KJV
But I, as a deaf man, heard not; and I was as a dumb man that openeth not his mouth.
Psalms 38:13, King James Version
In context
12 They also that seek after my life lay snares for me: and they that seek my hurt speak mischievous things, and imagine deceits all the day long.
13 But I, as a deaf man, heard not; and I was as a dumb man that openeth not his mouth.
14 Thus I was as a man that heareth not, and in whose mouth are no reproofs.
