'Tongues' in the Bible

And they bend their tongues like their bow for lies: but they are not valiant for the truth upon the earth; for they proceed from evil to evil, and they know not me, saith the LORD.

Each one betrays his friend;no one tells the truth.They have taught their tongues to speak lies;they wear themselves out doing wrong.

Their tongues are deadly arrows—they speak deception.With his moutha man speaks peaceably with his friend,but inwardly he sets up an ambush.

Behold, I am against the prophets, saith the LORD, that use their tongues, and say, He saith.
