'Dumb' in the Bible

Let lips of falsehood become dumb, That are speaking against the righteous, Ancient sayings, in pride and contempt.

But I, as a deaf man, heard not; and I was as a dumb man that openeth not his mouth.

I was dumb with silence, I held my peace, even from good; and my sorrow was stirred.

I was dumb, I opened not my mouth; because thou didst it.

To the Overseer. -- 'On the Dumb Dove far off.' -- A secret treasure of David, in the Philistines' taking hold of him in Gath. Favour me, O God, for man swallowed me up, All the day fighting he oppresseth me,

To the Overseer. -- 'Destroy not.' -- A secret treasure, by David. Is it true, O dumb one, righteously ye speak? Uprightly ye judge, O sons of men?
