'Mouth' in the Bible

Suddenly, Zechariah could open his mouth, his tongue was set free, and he began to speak and to praise God.

just as he promised long ago through the mouth of his holy prophets

All the people began to speak well of him and to wonder at the gracious words that flowed from his mouth. They said, "This is Joseph's son, isn't it?"

A good person produces good from the good treasure of his heart, and an evil person produces evil from an evil treasure, because the mouth speaks from the overflow of the heart."

Without warning a spirit takes control of him, and he suddenly screams, goes into convulsions, and foams at the mouth. The spirit mauls him and refuses to leave him.

"Why do we need any more testimony?" they asked. "We have heard it ourselves from his own mouth!"
