'Speaker' in the Bible

and Jehovah saith, Who doth entice Ahab king of Israel, and he doth go up and fall in Ramoth-Gilead? And this speaker saith thus, and that speaker thus.

A rash speaker is like piercings of a sword, And the tongue of the wise is healing.

They have hated a reprover in the gate, And a plain speaker they abominate.
